People have recommended Bill Hicks almost as a gold standard. He was anti-social before it was cool and I’ll give him that. His comments on drugs could be insightful. But there is much more to being anti-social than just bashing christianity. Plus I never thought he was very funny when I listened to his albums. I like funny comedians with good social commentary that is a mix of insightful and cynical, but Hicks wasn’t anything special to me. His bits on smoking never interested me.
Carlin was better, but Bill Burr and Doug Stanhope are arguably the best comedians at both being funny and insightful while addressing social issues. Aside from them Patton Oswalt, Louis CK, David Cross, Bill Maher deserve honorable mention.
