never a jw: Have I been unlucky in my deals with black Americans and lucky in dealing with black Africans
Africa is not just one country, cultures and customs can change from one place to another; your experiences with some Africans are not an absolute reflection of their people. You will find good and bad like any other place.
Just the same your bad dealings with certain American Blacks will not make the whole community bad, just like bad experiences with Anglo's, Hispanics or any other culture don't reflect the character of all of them.
