Black American culture has elements of Marxism in it. But it is the black culture that is uniquely self destructive, and separates itself from all other forms of Marxism.
No, it’s not the “culture” since it is not a plurality of blacks that even give that way of behaving any credence. It’s Marxism. I have seen lots of whites in Europe going on the exact same way.
Marxism has been all over Africa too since decolonization. All of the “big man” dictators owe their destructive philosophies to Marx in one way or another.
You should go to Fred Reed’s site and read his take on cultures and diversity. He pulls no punches.
