Fine, liberals like him. That doesn't mean everyone does.
Just come out and say that he's an extremely successful comedian. You don't have to agree with his politics, but don't make yourself out to be a partisan fool by denying his success.
I don't deny his success, I'm just pointing out that he is only funny to people who share his political views. The rest of us don't see the humor in some stuff shirt calling somebody names like a 14 year old. To rational people, there has to be an element of truth for something to be funny. What he is saying is only true to people like you who are motivated by hate. A true comedian doesn't have to appeal to hate to make people laugh. If he's successful, it's not because of his comedic talent.
