Why does my family criticize me for the race of men I mainly like?

I don't judge on appearance and I don't go hunting for a relationship. I usually start off friends with people and if I go so far as to have them as a boyfriend, then okay. However my family makes fun of me because I mostly like black guys. When I was little my cousin touched me sexually and ever since I can't be close with white males, which is what my family prefers. I've made comments about guys like Drake, like "he's so cute" so my family is aware of my attraction to black men and they despise me for it. Not my fault! It's not like I only like them, I like puerto ricans, indians, blah blah blah etc but this annoys me. My aunt says, "well she's half Sicilian guys so I expect it, she isn't full white" but Sicilians are white, soo why do they pick at me? Damn..
