TA is arguing whether steroids are "good" or "bad".
Everyone else is arguing whether they should be legal or illegal.
It's NOT the same argument.
While everything TA is saying about steroids being "dangerous" or "bad" may or may not be true, I utterly reject the notion that in a free society someone else had the right to tell me what I can or can't put into my own body if it doesn't effect them.
TA made his own decision about steroids, as is his right. He doesn't, however, have the right to make mine for me as well.
