Some interesting points made here, also some good arguments in favor of conservatism... I'll just quickly add my two cents on some issues:
First off, I guess I'd most definitely call myself a liberal, and although I do not live in the US, I generally agree more with the agendas of the Democrats than those of the Republicans. And there are a few key issues that are the reason for that.
1) Interestingly enough, the point of liberals/Democrats being too "politically correct" and too soft versus their opponents, has been raised. Now I do agree that while the "puss-out" (since that term has been mentioned) way is a lot less flashy and a lot less impressive, I'd take that road over the Republican Over-The-Top-style any day. Why? Simply because this thing that has above been mentioned as "saying out loud what you believe and want" does nothing but build up and strengthen already existing ressentiments, and add fuel to already burning fires. It is, simply said, a most undiplomatic way of doing business. I always like to put it this way: "Those who shout the loudest usually have the least to say." - Because if their ideas were sound, and their arguments reasonable, they would not need to "shout out"; for people would listen to what they have to say anyway - simply because what they have to say makes sense.
Now I do believe that this has something to do with the American mentality in general, as the US tends to see itself always "in the right", no matter what they do, once they've decided on a way to go - and there never occurs to them the chance that in fact, they might have been mistaken. Once a course is set, that has to be followed to the end - and to whatever end, at that. And I just don't think it's smart. It's just stubborn.
I understand that governments oftentimes will have to go through with their set courses in order not to appear spineless, but ultimately, pursuing a course just to finish it at whatever cost, even if halfway through experience begins to show that it's been the wrong way to go to begin with, to me is not a sign of strength and rigidity, but a sign of weakness, in that it shows people's inability to admit to own faults and mistakes, which in my opinion takes a lot more "guts & balls" than to just keep hammering down on an issue until everyone else is silenced by brute force and grind. And I simply get the impression that the liberal/democratic way of handling issues is more akin to the latter, hence my preference for it.
The problem with being too up front and too much "in your face" against others is that, while a nation like the US due to its size and potential power (both financially/economically and military) can often overwhelm a potential adversary or counterpart or at least intimidate them into submission, is that even though a momentary victory might have been achieved, the underlying conflict almost never is resolved. And by being too much of - plainly put - an a**hole about it, it just adds more fuel to the fire. And ultimately, those conflicts will boil up again, and the sh*t will hit the fan even more dramatically and drastically than before.
That's why diplomacy, especially in an international context these days, is more needed than ever. And Republicans/conservatives often lack that diplomacy for me. For after all, one of their main agendas - and of course, a very legitimate one - is that they will always put their own nation's needs first. That of course would appear very patriotic at first glance, and very beneficiary to the people living in that nation. However, it is my belief that in our day and age, the times of nationalism are (or at least should be) over. I think that the entire world these days is confronted with pressing issues that affect every nation and every person, and not just the citizens of one particular nation anymore. And I belief that the entire world will need to find a way to act together and to cooperate on some of these issues in order to steer the course into a safe future. That sounds very utopic, of course, but that's just how I see it.
But of course that idea is often corrupted by problematic decisions and attitudes of nations' leaders, and to me, conservatism/nationalism lies at the heart of this. For when everyone is always only focused on their own well-being instead of looking at the "bigger picture", someone (usually that party who has more strength/power) will come out on top, while the other (the "underdog") will have to submit to the stronger one's will, and again just fueling the initial conflict. And you can see that problem in countries all over the world. Take for example the still communist countries of China and especially North Korea, that are literally trying to completely seclude themselves from the rest of the world (which is absolutely ridiculous in my opinion, as they are, as a matter of fact, also part of this world, and no indoctrination of the people in any beliefs whatsoever by their governments and leaders will ever change that simple reality); and there are still governments where religion/spirituality plays a way too important role, and which are thusly restricted in their options of acting in a holistic way; but there are also western governments, mostly those led by conservatives, who simply focus too much on their own agendas - always in the mindset that they only want to do what is best for their people, which is patriotic of course - without ever looking left or right, and without ever trying to look past what's right in front of them. And of course that seems like a safe way to maintain the status quo (also a point that has been raised), since the status quo is something that is known and something that we can deal with; any major change always comes with a risk of failure, and people are naturally scared to take those risks (also quite understandable) - but I simply believe that in this day and age, a maintance of the status quo is no longer an option, and changes to socities, both within the microcosms of societies within singular nations as well as the global society as a whole, have to be targeted and have to be achieved in the next decades in order to preserve the world we live in for future generations, and to avoid another great (possibly nuclear) war that would in any case threaten the existence of mankind as a whole.
And to achieve that end, both the acceptance and readiness for change, people of all nations, all beliefs, all creeds and all color need to be brought closer together and taught to understand that ultimately, we're all sitting in the same boat - and in the long run, it just won't matter whether your house stands in Washington D.C., in London, in Nairobi, in Tokyo or in Beijing; whatever happens in this world meanwhile affects us all; even regional wars and conflicts affect worldwide economy, and the bigger the conflict gets, the more nations and people will be pulled into the maelstrom, one way or another. And we should do any and all things possible to prevent the rise of more conflicts, and the aggravation of already existing ones. But in my mind, that can never be achieved by brute force, but only by reason. Only if people are educated to understand this situation, and only if they thus become ready to pull on the same string, progress can be made. And that is why I think a diplomatic approach is needed; for a greater basic consensus to work off on is needed. And a consensus simply cannot be forced, by nature.
Hence my affinity to the "liberal/democratic" way of doing things.
2) God. My dear, what an issue. It should be over and done with for a hundred years, but STILL people keep bringing God/religion into the equation. And to me, as an agnostic (not an atheist!), it is just beyond ridiculous. Grown men and women, who are trying to discuss important decisions that affect the very way a large society will develop, suddenly and completely inexplicably oftentimes fall back on a purely transcendental, purely hypothetical, purely imaginative "entity" as an argument for or against certain processes, acts and facts that exist in real life.
I simply will never understand how on Earth people think it could in any way whatsoever be reasonable to justify ANY decisions whatsoever by bringing in the argument of "God wills it!" - For there simply is no proof, no evidence that this "God" even exists, much less so any proof or evidence that we, as this God's alleged minor underlings, even have any clue of knowning that the true "will" of this entity really is; to claim such I think is just a complete paradoxon of the entire concept.
Now as Davi323 pointed out: If you have scientific and reasonable arguments for something, by all means, be my guest. If you are against abortion, and you explain to me exactly why and how an organism that consists only of a handful cells already is to be regarded as a human being, and if that argument is sound and reasonable, then I will listen to you. But if you tell me that abortion is wrong because "God says so", then I will gladly call BS on that!
Same thing for gay marriage/homosexuality in general. Now apparently, homosexuality is a sin, right? Because people can't reproduce in gay relationships, right? And because the bible says so, right? But then, tell me - if that "God" is so omniscient, and so omnipotent, and created everything and everyone around us insignificant human beings according to his own will... then why has no one ever mentioned the idea that homosexuality could possibly be a part of that plan?! I mean, it's not like there are only 10 gay people worldwide; I think there's quite a couple more. And if there are that many, the conclusion lies close at hand that God made them so - and suddenly, those who are most zealously defending their "God's" will, in the same breath and instant proclaim a flaw in "His" design?! What kind of logic is that?! And who are we - especially those of us, who so blindly and faithfully trust in "God", or rather, the teachings of that God's church - to claim to know better than that divine entity itself?! Oh of course, it's in the bible... but then again, the bible was written - guess what - by PEOPLE. And can't people make mistakes? Couldn't it be that someone maybe just deliberately put that in there, because they didn't like homosexuals for some reason?
I am sorry, but that entire discussion, to make an entity, that only "maybe/maybe not" exists the entire basis of ANY argument for anything in the existing world, to me is just beyond ridiculous.
If you have faith in God, if you are follower of a religion - by all means, please do so. Please go to church every Sunday, please pray for the safety of your friends and family each night before going to bed, please read the Bible, the Q'ran, the Tora; whatever suits you - but please, please, PLEASE keep ANY ideas you get from those teachings, any ideas you get because of your relationship to that entity you worship as a "God", OUT of politics, OUT of law, lawmaking and the entire apparatus of justice, OUT of any form or fashion in which YOUR beliefs could be employed to suppress the lives of others, or where others are forced by governments and laws to live the way you choose fit for yourself, even if they do not. Because that has NOTHING to do with "being good" or "doing good"; that is simply cruel, inhumane and fascist.
I guess that's my take on Kant's categorical imperative: "Act only according to that maxim whereby you can, at the same time, will that it should become a universal law."
And really ask yourself, whenever you form or voice your opinion on a subject, especially if you think that your own personal religious motivation might have played a role in forming that opinion: "Do I really believe that this/my opinion should be made a law; a law that is binding to everyone, even if they do not share my belief/faith? Or - could it be enough if I just for myself follow that belief (i.e. never carry out an abortion, never marry a person of the same gender etc.), and let others do what is right according to what they believe?"
It is a matter of freedom; something that I think especially in America is and has always been a great word and important principle. And especially for those who claim themselves "patriots", who claim themselves those that work in the spirit and for the good of their nation - is there still freedom if I force my will/my faith onto so many other people, even if that faith is not theirs?
In closing, I will just quickly reiterate: Keep religion out of politics. Please.
And yeah, I guess I'm a liberal. ^^
