I have to agree with Xemnas to a greater extent, you need a balance because freedom is good, but too much of it will only cause dissent. "Freedom" is a bizarre concept. You are, if you should so wish, "free" to break the law, "free" to resist arrest, "free" to kill loads of people. But then you're putting the risk of others' "freedom" because, as Xemnas mentioned, of chaos. That, in this extreme situation, had been perpetrated by you the murderer. But others are also free to try and stop you or to resist you. Say you're one of the murdered. Your freedom has been snatched away unjustly, and that's just not cool. Should anyone really be free to take away others' freedom? I don't think so.
However, while I agree with a lot of what Xemnas said, I think it's important to remember not to get too pedantic over the use of a word, especially when that word defines a culture. When people say "freedom" in that American sense, they're talking about something much more general and good-natured than what I was saying.
Let me give you an example. About a year ago or so there was some law suggested in the UK that youths could no longer be arrested for swearing at police, because apparently they're free to say what they like. I personally thought this was an outrage; you shouldn't be allowed to swear at anyone just because they work for whatever law enforcement, disputes on the efficiency of said law enforcement aside.
On the other hand, this News of the World story. For those who don't know, a newspaper in the UK got shut down for phone hacking, illegal exchanging of personal details etc. I don't know the whole story and it's probably been heavily distorted by now, but I do believe that people should be free to protect their privacy, and I don't think you should be allowed to breach it. This was one breach of freedom, caused by others' exaggerated sense of freedom, that I was disgusted by. "We're allowed to do this, it's our responsibility to give the public information." No it isn't. It's you're responsibility to do so in an ethical and sensitive manner. But then, we are talking about British media, when is that ever ethical and sensitive, really?
So to summarise, I think it depends how and when you apply the word, as to its true definition. Total true freedom, in its purest sense, would result only in anarchy and chaos. There has to be a boundary so people know what is and what is not acceptable. But it's no bad thing to have a generally positive concept to rally a nation around.
