A slave mentality resulted from being raised in a white dominated society. They perceive black as being inferior, so they want to compete with it, dominate it, and challenge it. This is why black people hate on each other, kill each other, bleach their skin, act white, distance themselves from black culture etc. etc.
That's what happens when you're brought to this country and treated as an animal and 3rd class citizen for the majority of your stay here. Also having white standards of beauty and standards of conduct, because when you go somewhere and wipe out the natives and claim the land as being yours, you can establish whatever standards you want. Especially if you keep the remaining people docile and complacent with your white jesus religion bs.
