My favorite comedian and person of realistic thought is Bill Hicks. I am also a fan of Christopher Hitchens. Reason, logic and science are my go-to ways of life. I prefer a democrat way of thinking and I don't tolerate intolerance.
Yeah, Hitch is one of my all-time favorite people - he is sorely missed.
If you are looking for good atheist comedy may I humbly suggest Tim Minchen. He does his comedy through music but it is hilarious. Look for him on YouTube. My favorite is woody Allen Jesus.
I’d forgotten how funny, in his antagonistically atheist way, Bill Maher is! Been watching all I can find. -- recently out of the Oregon woods and new to ‘unlimited high-speed internet’ - damn, there’s all kinds of good stuff out here
He can be a bit caustic, but I do enjoy much of his comedy.
