I don't think that the argument of "If Bonds/Clemens, then everyone" holds. The reason that Bonds/Clemens get votes is their relative positions as arguably the greatest players in the game over their respective careers.

Clemens is arguably the top RH power pitcher of his generation.
Bonds is arguably the greatest power/speed combination of all time. He holds the all-time and single season HR records.

Even if we lump all PED users into a "PED pool," it wouldn't change the fact that these two individuals were exceptional among that pool.

Let's assume for a moment that all players in the 80s/90s/00s were PED users of some sort or another. You'd be forced to either ignore a generation of baseball or, at least, pick the best of the best:

Greg Maddux - Best finesse pitcher of the generation
Randy Johnson - Best LH power pitcher of the generation
Pedro Martinez - Best RH peak power pitcher of the generation
Roger Clemens - Best RH power pitcher of the generation
Mike Piazza - Best offensive catcher of the generation
Barry Bonds - Best offensive player & power/speed combination of the generation
Rickey Henderson - Best speed player of the generation
Tom Glavine - Possibly best LH finesse pitcher of the generation

I'm sure I missed a lot of players, but that is what I view as a list of players who would be arguably in, even if they used PEDs... along with the rest of the game.

Now, after that top tier of players, I would ask "Did this player use or was he suspected of using PEDs during his career?"

That's why Bonds and Clemens in, but not the other PED users.
