On PBS about two years ago they had a documentary on Africa. And it was hosted by Henry Louis Gates Jr. Actually, it was a pretty good documentary. When it even broached on an Afrocentrist viewpoint the response was it might be that way or it might not be we don't know. The historic revisionism was kept out. The thing most irritating was that everywhere Gates went, and it didn't matter West Africa, Ethiopia, East Africa or Zanzibar, anyone, who he ran across whose ancestors had taken slaves, he'd asked does it bother you that you may have enslaved my ancestors? After a while it became so cliche on his part to be bothersome. I found myself saying to myself, "Mr. Gates your ancestors are from West Africa--why are you embarrassing these East Africans etc. with this question."
It became quite apparent that this guy has a problem with the fact that some folks enslaved his ancestors and they looked a lot like he did.
Facinating insight into the issue; and, the man.
...but, I'm afraid there's little profit in insights; of, either.
