Actually, you're just a motherfucking chump.
You can hide behind semantics and ignore the obvious, but at some point reality has to set it: these guys dope. Nearly all of them do it. If you're saying that's OK, then fine. But if you're arguing that they absolutely clean because they haven't been caught, then you're - you guessed it - a motherfucking chump.
I consider myself a liberal, and it pains me to take this position, but this sport is dirty to the core at the professional level. I'm almost ready to consider all top riders dirty until proven otherwise. No one at the top levels - be it riders, managers, owners, or organizers - has done anything to earn my trust on the subject of doping.
