pretty much since you're black anyone who is not black will have hard time dating you without being labeled as some bbc chaser which is not a pretty look for anyone who isn't into that or degrading, interracial with others is much easier since it will only be under the generic term of that and has less of a negative stereotype associated with it (except for asians going for whites because gaijin hunters)
in the end that's all just bullshit that porn is pushing on people but insecure people won't want any kind of negative labels on them out of fear of social disgrace and becoming excluded and for some people "racial purity" is a thing too even if you're both guys and won't be popping out any mutts
