Why do people think black girls are ghetto ?

i hate when people say we are ghetto and we dont carry ourselves well, especially the people who havent even been un the black cumunity or evn befriended a black person. the majority of the time i see white chicks acting crazy. i know some crazy black chicks but the carry them selves very well. i hate that people say we are ugly. i know that that can be someones preference..but someone can still be attractive and not be your type. i ONLY know pretty black chicks. but the truth is ive seen ugly in white. and evry other color.i hate people who say that we are ugly ... but in hollywood thngs that people want are curvy bodies, high cheek bones, wide eyes, full lips, and thick hair and we have that. i hate ignorent people smh
