Which culture are you talking about?
There are dozens and dozens of African nations and many different African tribes, and many centuries of blacks living in various cultures globally.
Do all blacks everywhere and through all time only have one culture? It sounds more like genetics than a culture.
I’m not certain that Blacks have the same problems in different cultures. I do believe they have a strong influence from Cultural Tribalism. It is a culture that has as it roots a tribal function. One persistent characteristic is its rigid tribal model that discourages any variation from the norms of the tribe. It is a culture so rigid that it maintains that basic form even when it lives in other cultures. Cultural Tribalism is a model that takes generations to change.
As you may know, the Left is trying to instill tribalism into our cultural system. We have heard the phrase, “It takes a village to raise a child.” In this case, it has motives with totalitarian Marxist dimensions. Blacks are vulnerable. They may be an easy target for this move as they are controlled on the Democrat-Marxist Plantation. It has succeeded in removing the father from the family, which has had negative consequences. It will affect each generation. Once Marxist tribalism is instilled, it will be hard to break through its rigid hold. That is the plan.
