Do you not watch any movies produced by Weinstein? Kevin Spacey? Marlon Brando?
I'm so terribly disgusted by Cosby, and all these creeps. At first, I thought I should boycott their work. But it's too endemic in Hollywood--you'd have to boycott everything. So instead, I focus what was on the screen. Was the film/show uplifting? The Cosby Show was, and the other actors/actresses have been victimized by Cosby's sins as the show has gone off syndication and they are no longer paid for it. But that's not really fair to them ... the show was bigger than just Cosby, and was known for getting a lot of up and coming actors their start.
So I choose to just enjoy it for what it was, which was a great show about families.
