We knew that these structures were built by sub-saharan blacks in the same way we knew that the civilization Greek and Romanian built by white Europeans .
I feel this comment is very demeaning towards black people.
Also I'm tired of having to deal with the constant whining. there's a reason why black folks are the way they are.
I don't agree of your viewpoints of thinking black people are uncivilized. I think it's a terrible generalization in my opinion. The black community have done many great things for society.
