Cheating is cheating, you are right. But life is made up of shades of gray. Otherwise, jaywalkers and murderers would be lumped together.
Sure, but we're not talking about sentencing criminals. We're talking about enshrining players into the hall of fame. A lot of people bring up the message you're sending by allowing Bonds, Clemens, etc. into the hall. What message are you sending when you say some banned substances and practices are ok but others aren't? (ironically "greenies", the banned substance that is ok to take, are much worse for you medically than steroids)
