He said things like gender, race etc aren't factors in who he has on his show, because race/gender have nothing to do with how funny a comedian is. And he's right. He's had women and black people on his show. One can assume it's because he thinks Dave Chappelle and Ellen Degeneres etc are funny.
Race and gender have nothing to do with how funny someone is, it's true. But race and gender are absolutely factors in who Jerry has on his show because race and gender play a big part in who is considered funny and who gets opportunities. In other words, he's drawing from a talent pool that is shaped in large part by racism and sexism. Unless you think the fact that the vast majority of stand ups being white men is simply because they are actually funnier, then you have to concede there's something else going on.
This is how a person who isn't racist or sexist thinks.
No this is how a rich old white dude who has never considered these things thinks. I doubt Jerry has ever given a passing thought to any social issue outside of age of consent laws.
