Why do alot of black women treat mixed girls so mean?

I'm half black half Hispanic and when I was younger from elementary and up black girls always had a problem with me. Not all but a big portion they would always say I was trying to act white because I didn't talk like them, I wasn't loud, I didn't like rap music and I didnt dress like them. (not everyone acts the same geez). Alot of them would say I didn't have black in me cause my hair is long and I'm very light it just aggravated me because they would say I didn't act like I was black and I'm like WTF is acting black. They also said my parents weren't divorced only because my dad is Spanish.. Did anyone else go through this?
