I didn't mean to sound sanguine. Although I agree that if everybody dopes, then, as far as the sport goes, it's not different from everybody having access to a certain level of equipment, I also agree that the effective necessity of doping is a health risk to athletes that it would be much better to avoid.
The only difference, for me, and it was not anywhere in the above message, is that I don't think the blame for doping should be placed on the athletes. If the expectations of the sport necessitate it, you have to ask where the expectations come from. When Barry Bonds looked at Mark McGwire, an athlete altogether inferior to him, being adulated because he took steroids and hit homeruns (and Bonds is quoted to this effect), the conclusion seemed no doubt clear. If there is blame for him reaching that conclusion, it should be placed where it belongs, on the fans and sportswriters doing the adulating and not caring about what was in front of their eyes (and indeed known to the extent that androstenedione was seen in McGwire's locker and people just decided not to pay attention--yes it was not illegal then, but it was a known steriod). I think much the same can be said of biking. If we want athletes to stop doping, in addition to all testing, we need to be skeptical instead of adulatory at certain levels of achievement, as mean-spirited as that may sound.
