Reared/fostered in a white family, white friends, an ultra-conservative value system is, if the person is of African descent, will be very impressionable to anyone whether being any color, creed, or previous religious upbringing.

There's a good example in the series House, MD. An Indian doctor's Indian parents were killed in an armed robbery of their convenience store. His white foster parents encouraged him to keep his Indian heritage, but was just as white on the inside as any white person. He liked video games, collecting blasters that were used in Star Wars movies, had a deep understanding of European derived culture that was in "normal" America. Instead of using a ton of garlic in his cooking, he liked tacos, burritos, hamburgers, hot dogs, pizza, etc.

My point is environment can be more important in the development of a youth than genetics. If you're reared in a crappy environment, you have to be extra vigilant to not fall into gangs, drugs, etc.
