He’s basically the male version of Oprah. He has a lot of time to fill, so he invites on tons of grifters and crazies, including many alt-right, and lets them spew their bullshit mostly unchallenged.

He platforms people with dangerous views. Friends with Alex Jones, etc.

He also calls himself a comedian and as a person with a sense of humour I find that offensive.

He just enables the other dumbos by giving them platform and not questioning them at all.
