Eh, it can definitely be a fetish or even dehumanizing but just liking or even preferring it isn't that deep; especially if you're a black person. There's a certain amount of mental projection that goes on when consuming porn that I'm not afraid to admit and I understand that for a lot people there's an unconscious preference for being somewhat of the same ethnic group as the dude performing. Like if I'm a straight Black guy it's somewhat natural to want to see somewhere in my lifetime porn consumption of men who look like me and women who desire someone who looks like me. It doesn't have to mean that I'm opposed to white guys or anyone else getting theirs, it's just, you know, that projection at work. I get it.
Like I don't think it's weird for say, an Indian dude to have somewhat of a bias for porn where the dude is also Indian, whatever else the other performer happen to be, gender, ethnic group or whatever. Like that, I get. Even in porn representation does amount to something, yeah?
Aside from that quirk though IDK yeah some people are definitely weird about it. It's doubly weird when you're not of that ethnic group.
