Lance Armstrong is guilty. This guy is so competitive that he would never walk away from a fight if he knew he was NOT guilty. Because he is guilty, at least this way he can still bullsh1t the people that are too stupid to see the obvious truth. A man like that does not back down when they have righteousness on their side. To keep fighting would have destroyed all doubt and made him a permanent punchline in the sports world.
Considering the whole tour de france was doping, I don't think he should lose his titles. He passed the tests and the tour didn't dig deep enough. Taker away any speed/time records, but not the titles. All his real competition was doping too. In that respect it was a pretty level playing field. It only sucks for those guys who weren't as good and would have had to dope to compete but did not dope and therefor did not come close to winning.
Also, this has nothing to do with cancer and what he has done with that. If you used to support his cancer fund, no reason to stop now. It's good works, he needs to just stick with that for now. But I would suggest you ditch the bracelet because it was tied in with his "winning spirit" and clearly cheating is not being a winner. Now he is simply a survivor, not a winner. Had he admitted it right away, I could forgive, but cause he continues to lie to everyone he is not a righteous man.
Any half assed lie spotter could tell he has been lying all along. It's almost as bad as Clemens weak lies, and that show was pathetic. I looked up to that fool when I was a kid.
