There is a difference between black, african-american, and nigger. Black is the most general term, AA is an actual Americanized African, and nigger's a black person who acts like a douchbag. Just like how gay and fag are different. Gays are homosexual. Fags are dipshits. Like Justin Beanber. He's not gay, that's an insult to the gay population. He's a fag.
