How nonsensical that the only valid critique could be from fellow dopers (who cheated their way to "success").
A (most-likely natural) winner like Burfoot is not allowed to comment on his sport's records being disrespected because he hasn't doped his way to a higher level of success?
Next, they'll be saying only dopers can comment on obvious doping because they have experience of doping.
They tried to shout down Greg Lemond's remarks on Armstrong on the same basis but look how that turned out!
