Wow wow man, hold on your horses for a minute here.
You are rambling and it seems like you are really pissed off about the mather but lets look at it in a calmed way.
First of all the topic if you have the time to read it has been splitted half and half because half of people wants Shawn to win because they don't want to retire and half want (myself included) the Streak to go on because the WWE has sold us the Idea of the Streak being a big deal and a big part of Taker's legacy, truth be told I bought their koolaid and wants Taker to win, but if does not, I would be very pissed off but won't riot.
Now you are putting HBK like he has been mistreated by the WWE since 2003 and Taker being the politic with huger of power and that is holdign Shawn back, whci is really a bad arguement and cannot be further from the truth.
The only reason why Shawn has not being champion is because he does not want to, it has been reported that he has been proposed to become champion multiple times but he refuses to it, because of what it takes in the matter of tours and house shows and time. If Taker is battling through Injuries so is Shawn and more than that, Shawn is the one who has hinted retirement, not Taker.
Taker has won the title 3 times since 2007 and although he is battling through injuries he gets there and puts on a show too,before he lost the tiltle to Edge, he got injured during a house show and was said to be on the best condition of his life, actually it showed druing that time but the injury came along, never the less he battled injured during two brutal matches to lose the belt in the ring an by being stripped due injury.
Even if you question why he got it you have to respect the fact that he gives it all when he is in the ring, The Man got burned before the EC and still wrestle during the event, sure he was pissed off but he wrestle none the less.
Besides you need to get your facts straight: Shawn's record at Wrestlemania is better than you mention:
2003-WM19-Won over Jericho.
2004-WM20-Lost to Benoit, actually he didn't but he didn't won either.
2005-WM21-Lost to Angle.
2006-WM22-Win over Vince MacMahon.
2007-WM23-Lost to John Cena.
2008-WM24-Win over Ric Flair.
2009-WM25-Lost to the Undertaker.
So it has pretty much being an interval of a year between wins and loses for Shawn.
On the Storyline of Jericho beating the living crap out of Shawn, it was just one win over him (During the storyline, because later Jericho won when he was champion in a ladder match) during the entire feud, and in the last match it was Shawn getting win by beating the living crap out of Jericho. Same with the JBL storyline, in the End Shawn always get even.
I know Shawn is humble, but by no means he is a saint or a martir who puts everyone over, neither is Taker as a matter of fact.
They took almost the same time off, while Shawn put over the Undertaker (who put Shawn over dring the end of 1997 and the beginning of 1998 with out getting a win back) the Undertaker put over the Big Show in clean fashion before getting out.
Now tell me how many people has Shawn put over since? on his DX stint, they got defeated once out of 3 times with the last one being very bad for Legacy, Shawn took all they had to give and still survived.
Orton on Raw? part of the storyline and was with a rollup, nothing really to brag about. HHH and Shawn never put Jerishow over, not once, so much that they looked as a joke, not as the most dominant force in the WWE.
On Taker's side we all know that since he became Champion he ruled Smackdown and only lost to Jericho and not cleanly.
So this humble guy that puts on unique shows and never gets anything back story you want to made up is far from the truth since at least he got the Tittles for a while and all of the sudden the tag matches became all the time the Main event, title or not.
Now does Shawn deserves to win and end the streak? man his history gives you that he deserves it, I don't want him to do it but he is deserving of it. Does Taker deserves to win at Mania again? Of course he does, after 20 years in the busines and even when the guy is broken comes back and put on a show, damn he deserves it, even if you don think so.
Now take also on account that if Taker's win, is not because Taker wants to or he played politics againts Michaels to do so, if that were the case they would not face each other again, like when Hogan played Shawn into the Summerslam match and then wanting to win again in a steel cage match, that time Shawn just agreed to one because Hogan refused to put him over. If Shawn loses s because Shawn is ready to retire at least for a while (3-4 months).
What the Treath is about is that people also looks to much into it with the career stipulation, as it seems it was only thrown to put people againts Taker because none wants Michaels to retire or think he is ready to do so. It portrits Taker as the bad guy and Shawn as the Underdog, and more with the damn promo from last week when Taker was too respectful and Shawn owned him in the promo, just like last year, but last year was different because it was Shawn mocking him with nothing on the line, now he mocks him but since his career is on the line, Taker is now the bad guy because he wants to end Shawn's career? How dare he? Who does he think he is? Well He is The Undertaker and if Shawn is going to retire againts someone, why not the guy who has been there through Hell and high water? The guy who is a counter stone of the Damn Company and has been there during almost 2 decades just like Shawn? The guy that when everyone disliked Shawn was there to work with him and not complain at all?
A lot of fans love the Damn Streak (I actually like it) because it something unique, but a streak with a defeat is meaningless, as simple as that, with the career stipulation everyone is jumping to conclusions that Shawn won't retire and the Streak will end for nothing (which is not entirely truth, since, I mean is Shawn Michaels we are talking about here), and that is also pissing a lot of people.
I mean both men are deserving of a victory but putting Shawn as a martir and Taker as a Politician that is only there because he is greedy is BS and you know it. None is going to riot no matter the result.
