A certain segment of the black population's behavior is just so textbook.
If their behavior is poor, they either claim it isn't really poor and you're racist for pointing it out, or else it's your fault it's poor.
If they haven't achieved artistically or intellectually on par with whites, asians, and middle-eastern societies, they make excuses for themselves ("it's white people's fault" is a common fallback) or else they try to take credit for other people's work (i.e., "black people invented ice cream" or "black people invented music" other such idiocy)
If they win or achieve something, it's because of hard work and determination, and the "specialness" of the black race. If they fail, it's because racists held them down.
If they commit a crime, it either isn't really a crime and you're a racist for calling it such, or else it's your racism which drove them toward the wrong side of the law.
If they want to recognize black achievement and support black causes, it's healthy. If you want to recognize white achievement and support white causes, you're Hitler Jr.
When rap is considered a good thing, it's theirs. When the negative aspects come out, "white people invented it."
If black people's behavior lazy, rude, stupid and obnoxious and just all around pathetic, it's because your standards are too high and you're a racist KKK member somehow.
Black people hate asians and middle easterners because these people come to America and usually find success.
Then we look at black people and wonder why they've been sitting on their duffs for several centuries now and their greatest achievement is break dancing and basketball, which, by the way, whites almost always win when in international competition -- both in dancing and in basketball.
