Like I said, if it was only the first one I'd have said it's a non-issue and should just be brushed off.

But he doubled and tripled down, taking it from a simple one-off "yo mumma" joke into some rather gratuitously explicit sexual comments. That's not a benign yo mumma joke anymore.

Besides that, the video does briefly suggest that according to some people, this is the latest in a line of sketchy behaviour.

It would have been so easy for him to apologise. Once he realised his behaviour was upsetting people, it really doesn't matter what else there is going on around it. The appropriate thing to do would be to apologise and reflect. And if he'd done that, this whole thing would probably not have gone any further. It would all have blown over in a week. His decision not to apologise is reminiscent of some centrist comedians who, when challenged about some problematic content of their work, decide to double down by swinging hard to the right. I don't know enough about the situation or the people involved outside of what's shown in this video to be able to say that that is what's happened, but at least on the surface, it kinda looks frighteningly similar.
