I agree with you.
Having worked with African engineers several times over the years, you find that they are not infected with “American Black Culture”. Nor, in fact, are their kids.
It doesn’t really matter who is to blame for it, its a real thing. The best thing that can happen is, if you are born into it, get out. Its not so strong among career military and their kids who are raised on military bases, for example. And if you have a chance to do a work assignment outside the US, whether Africa or Europe or Latin America, the best thing that can happen is to take the kids and go. Again, you’ll find that black kids who have lived abroad are much less affected by “Black American Culture”. And that’s a mercy.
You are spot on. Any black person who rejects the current black culture which glorifies racism, misogyny, lawbreaking, opposition to law and order, out of wedlock birth, rap, and other aspects of “gangsta culture” is almost always going to succeed in America.
And they will succeed because they are being part of America...not part of a dysfunctional, violent and repulsive tribe.
