I don't think it's an hypocrisy so much as a conservatism to avoid what happened to, oh, Fatty Arbuckle. Or HUAC'ers. This has waned a bit in the wake of Bill Cosby, but I always felt there was a desire to hold onto the greatness of these peoples' art for as long as possible before their reputations were sullied forever. Then again, The Cosby Show is back on TV in reruns, so what do I know.
