Seems to me that cycling has gotten so competitive that virtually all of the top performers are on some sort of drugs, like it's a culture there. If everyone is mostly clean and one guy is using special drugs, than it's easy to say that the one guy is a cheating asshole. But if everybody is using drugs and you basically have to to be competitive, then it's harder to judge.
Cycling has actually gotten cleaned up a lot lately. There are various teams with 'no needles' policies, and very strict monitoring of what people are ingesting in terms of vitamins and so forth.
Most sports are 'very competitive'. That's the point.
