True. My African refugee friends tell me some powers there wanted to keep only their own, because not all Blacks there are the same ethnic groups--biologically or culturally. So, some controlling powers do try to wipe out minorities.
That's why we don't tell them to go back to their countries.
But we know Blacks will never wipe out Blacks there.
Don't forget they have their own civil war in Africa. It's pretty much about ethnic cleansing either dethroning their king or some fake religious Christians killing off all ancient voodoo practicers.
