I was taking a course at a local college and the Teacher's Assistant (TA) was a very smart, clean-cut, black man from a western African nation. He wore a tie all the time and was very self confident as this class was a bust-butt kind of technical class. A few of us talked with him outside of the classroom one time.
The thing that the TA said to us that day will always be with me and changed my world view. He said (as best as I remember), "The American blacks are a disgrace to blacks everywhere".
When I was in college, SIU 67, the African students would separate themselves from the American Blacks in the Student Union. They were two separate groups.
There could be no stronger, greater race than the Black race IF and I say IF they would exercise discipline and integrity. You cannot get a finer person than Alan West, Clarence Thomas, Sowell, etc. but on the whole the Black Race is weak, foolish, and lost to any quality of life.
