I don't think its so much a hate thing, just don't think they see the future prospects and as a white man he doesn't want to see his Grandchildren come out black.. but thats a whole different topic (which has been done).I've said it before but this is EXACTLY why I wouldn't wanna have kids with a white woman.
My ex's dad is a black man, his son is mixed, son had kids with a white woman. Kids have light hair and blue eyes
Blackness gone in a couple generations
by gods grace my blackness will never dilute
you will still be able to see my wedge nose in my great great great grandchildrens faces
