Parents and sibling putting me down, a lot! How can i make it stop?

I listen to heavy metal and dont talk "black", my 'rents find it weird that I'm attracted to LOTS of white boys, I'm attracted to all races, but it's just that black males I see in my town dress in baggy clothes, and that doesn't attract me. I have lots of white friends too, which also contributes to what I'm about to say, I barely have black friends because they all think I'm weird, and white people are just a little more accepting of it, I'm not speak for or against these races, I am black, too. my parents and my brother are always calling me gothic/emo and insulting me about the things I like, they say things like "Why are you trying to be white?!" This upsets me a lot, was it a rule only white people dress/act a certain way that opposes to blacks? Im called "devil worshipper" by them, too. IM always being called a white girl, this hurts my feelings, but when I tell them to stop they ask "Why you so emotional?" then when I have enough I yell and they tell me not to be rude?
