Pryor's comedy was not for everyone, that is for sure, but he was a genious and should be remembered as one of the best comedians ever.
Yeah, no one denies his talents. The question comes when you stop and wonder how much, if any of it, sinks in. I guess it depends on how much an entertainer actual influences how we behave when it's time to take things seriously.
I second your opinion regarding Richard Pryor. I hope he rests in peace.
