This needs to be put into context. From the earliest days of the TdF doping has been ubiquitous, and if every winner who doped had his victory(ies) vacated because of doping the list of recognized winners would be a damnsight shorter than it currently is.
Armstrong isn't the first rider to dope, he isn't the first to lie about doping, and he's not the first to be a world class p'tit con. If you're going to despise him for these things you should have the intellectual integrity to also despise all the others throughtout the history of the Tour who've done the same things, even those who didn't profit from their treachery.
Don't misunderstand me -- I think Armstrong is a truly despicable person and that he has less personal integrity than your average crack dealer. Nonetheless I do give him credit for coming back from a nearly fatal cancer and going on to win 7 Tours, albeit by doping. Doesn't make him a good person but at least to me it's remarkable nonetheless.
