While I understand the point you are trying to make, the thing being called black culture is a symptom more than a cause the way I see it. For example, we have a huge population of incarcerated black men, the black population is disproportionately affected by poverty, we have issues with inner-city public education & discipline, and we have millions of kids put in inner-city environments where they are raised surrounded by gangs, crime and poverty.
For all these things above we can insert something like "Well, don't get arrested", "Study harder", "Don't glamourize gang violence". But stating these things doesn't change the reality many people are in right now.
Mentioned before that I've worked with the poorest of the poor in the city of Louisville. That definitely contributes to my worldview. Realistically, some of these kids just never have a real shot to escape (of course idealistically we can say everyone has self-determination, but I think the complexity of that is understated). Hard to type how bad some of those conditions can be. Like, we want to talk culture, and meanwhile we have 10 year olds with roaches on their bed pillows.
I don't know. I have thought a lot about this. I honestly don't have a solution, which is a kind of depressing thought. It's like death by 1,000 paper cuts.
