Lots of men find them funny.
That is disturbing in itself. I think whether they're wanking to it, or laughing, or both, finding enjoyment in watching women being racially abused, sexually abused, degraded is a real worry
There was a thing recently that said they did a study and men who had a woman be ?assertive made them have violent fantasies about women in general.
"Putting women in their place" is something lots of men approve of whether they explicitely realise it or not, and it's that,that a lot of this is catering to.
Also to dehumanise / other, which is necessary for the porn industry to keep going.
