He claims to be for morals and all of that, but he's had moments where he's exposed and he claims to be a father figure yet does things unfatherly. He curses (he's been caught cursing Russell Simmons out [not that Simmons is any better]). Cosby is also cranky.
Roundtree was rude at times and sarcastic, but at least he's not a hypocrite about it. When he wants to kick your a-- he'll do it.
I can respect the man behind Shaft more than Cosby. Plus Cosby said he supported Obama, so much for believing in responsibility.
