I don't agree on either of these points.

Women's attraction towards violent porn has increased in the past decade. That's not just a general thing about women, the problem is that women are more interested in more violence than normal, or in previous times. I still argue that that is a result of the feminization of men creating such a drought of strong masculine attractive figures in their lives, that they are fetishizing violence.

Blacks become a token of that fetiziation because of the cultural mapping of violent crime and aggression ascribed to blacks through much black media.

Now, I don't deny that blacks were fetishized by Social Justice. My citation is Fritz The Cat. However, I'd still argue this is an internal fetishization, not an external one. I also don't deny that women are attracted to some amount of violence & aggression as it can be used to denote a male capable of protecting them. However, the current trends are outside the norm.
