His humor directly relies on the fact that you agree with him. If you don't, he's not even vaguely funny, because he's an extremely caustic old bastard.
I think the problem is, he's very intelligent, but makes broad conclusions to be funnier. Don't get me wrong, he believes in the things he says, for example religion in the video. He disapproves of it, thinks it's negative thing to have existing in the world, etc. However, he realizes things are more complicated than what he says, that all clergyman aren't purposely bull****ting you, that a person isn't some kind of ****** or childish for believing in it.
If you know background on what he's talking about, it's funny, because you realize it. However, alot of people just like it because it's so condescending and insulting. I've tried to actually talk to people about religion, and they justify atheism for literally parroting things he says.
He really knows what he is talking about but acts like a condescending ******* as an act that is very funny. But he's the inspiration for thousands of condescending *******s who have no idea what they're talking about and thinks just making smartass comments and looking down on the status quo makes them better than other people.
