How is it dumb? Africa Americans are on average are a mixture of different African ethnic groups, this is fact. Whether you think it dumb or not is irrelevant.
Because Africans themselves mix ethnic groups all the time. You people always kill me with your 'expertise' off the top of your head having never been exposed ot the people you talk about.
I dont think the comment was dumb I
KNOW it's dumb because it has no merit, nor supporting data. People speak confidently on this board and know -10000 of what they talk about, yet feel confident to post dumb information. Research before making nonsensical posts about things you have no exposure to.
