You have drunk the cool aid. Sure, some violence is a family problem. Some addiction comes from living in a bad neighborhood. But nothing even close to these factors can explain the disparity of violent crime by race. See below.
If racism is recognizing this truth, your insult was well placed.

Don’t confuse cultural effects with race. Just because a majority of people living in a specific culture are of a particular race, does not make the resulting behavior genetic.
The *only* way you could claim that the behavior is a result of genetics (specific to that race) is if you could compare two different racial groups who have exactly the same culture and document differences in behavior that cannot be explained by any other cause.
The Vikings used to be brutes who caused fear wherever they went, because of their little habit of stealing, raping, murdering, and burning everything they couldn’t take with them. Yet here I am, married to a descendent of Vikings...and I am not at all afraid, nor have I ever seen him engage in those Viking behaviors. And I have never met a Norwegian who did not act civilized.
I can assure you that there are more violent whites in my mixed neighborhood than violent blacks (our next door neighbor has issues). And last I checked, the violent Islamists are still white.
Genetics is not destiny, but culture is.
Thomas Sowell has a whole list of white cultures where a particular group with high rates of violent crime got their act together and headed toward national norms. They were not violent because they were white. They were violent because of culture.
Same is true today. Nothing wrong with black people’s genes. Lot of things wrong with some black people’s attitudes and beliefs.
