I don't personally like the racial angle. I'm not white and I don't like my race or ethnicity being fetishized. I just like to see the biggest and hardest dicks possible fucking the hottest girls possible. Once race gets into it I get massively turned off. I like the brothalovers videos because their guys are always silent. One of my otherwise favorite videos is from BlackedRaw and what almost ruins it is the guy constantly saying shit like "that black dick feel good, don't it?" and "you like that big black dick?"
Clearly, as popular as interracially themed videos are (I don't mean just videos featuring performers of different race, but videos in which a white or Latina woman fucks a Black man to humiliate her white husband/boyfriend or says how much better "BBC" is) this is what the masses want, so people making porn keep churning it out. Most of the people into it are white men with their own attraction to Black men or Black men who feel good watching other black guys fucking white/light skinned women.
One of the reasons I like Damion Dayski so much is he's a really great all around performer. Huge dick, great stamina, has good chemistry with most girls and doesn't need to remind the girl and viewers every 5 minutes that he's Black. Can you imagine how irritating it would be if Girthmasterr and other white guys were saying "yeah, you like that big white cock, don't ya?" in every video?
