My Black people: why do "ghetto" girls hate me?

I have dealt with this phenomenon all my life. I have always been articulate, my mom is a teacher. I have always dressed well, kept my hair nice, spoken proper English, etc. In elementary school, all my friends were white. When I went to junior high, I started hanging with some of the black kids that I grew up with (the children of my parents' friends). They were cool, but other black girls from the projects and similar areas would call me "white girl" and ask me why I talk so "proper." In high school, they became more malicious. I had a brand new car at 16 and someone keyed it in the parking lot. I had a new suede coat and left it dd on the back of my chair and someone drew all over it in red ink. They hated me. In college, I never had the problem because I wasn't forced to ociate with those types of women. Now I work for the government and there are plenty of "ghetto"/ "hood" women in there with their Fantasia Barino rooster haircuts and Kool-Aid red hair, and they hate me too. I don't do ANYTHING to instigate these people. I carry my head high and I'm cly, I dress well and drive a nice car. I'm still articulate and intelligent but I'm never rude. I even try to go out of my way to be nice. They still roll their eyes, and suck their teeth when I get positive feedback or acknowledgment. They call me "saditty" and bougeios (or however these words are spelled!) behind my back, but I am a very friendly person! I have no problem with black women who are just average black women-- those who aren't at either extreme of ghetto or bougeios. i probably shouldn't care but my question is, why do they hate me and is there anything I can do about it?
