Yeah, I saw this on the news aggregates today. I said out loud "How is this news?"
But you bring up a difficult debate. Yes, performance enhancing drugs do change the game (some will say for the better), but how far back do you go? Some could say that chewing tobacco back in the 30s was a form of performance enhancement, and if so, should those players that chewed be removed from the Hall of Fame?
I actually prefer the asterisk next to the name. If you remove them, they just get forgotten. But if you leave their name in the Hall of Fame with an asterisk that says "By the way, this man was a filthy cheater, and that's the only reason he's in here." is far more biting and shameful than just being removed.
