I can't either. To be honest, I think his position of moral authority (I read a few articles about how he basically was viewed as/presented as a black success story/a black man who lectured younger black men on being better (being more like him in other words) and presented that image through his comedy as well as outside of it - this article discuss what i'm trying to say) makes the whole thing that much worse, and makes it that much harder to enjoy his acting ("America's Dad" rapes women!) and comedy routines because that moralizing or presentation was such a part of those earlier performances.
If I grew up watching those I'd feel more than disturbed by his behavior, I'd feel betrayed by the guy who always acted and preached so wholesome and turned out to be rotten to the core.
It's so much easier to still enjoy Remix to Ignition despite its creator's crimes, which are at least similar (certainly both fall in the class of taking advantage of women who lacked the capacity to protect themselves), than a bunch of conscious posturing and holier-than-thou-thus-listen smarm.
