Accidental incest in the African American community
A negative stereotype concerning African Americans is that the women are so promiscuous that the children and the mother herself are not sure who the father of her children are. In the poorer ghettoes this, unfortunately, is very true.
This situation, unfortunately, causes accidental incest. Half brothers and sisters get together and make babies and in extreme cases when a black girl has s** with an older man the man may be her father. This happened in Ohio.
Inbreeding is very bad.
