You can't judge all people of color because of one desperately fucked up person in a store.

You've also not bothered to look at the evidence I provided. And there is no video evidence of this:

Hatfields and McCoys, two American Appalachian mountaineer families who, with their kinfolk and neighbours, engaged in a legendary feud that attracted nationwide attention in the 1880s and '90s and prompted judicial and police actions, one of which drew an appeal up to the U.S. Supreme Court (1888).

However I suspect that a 'store' was damaged during the long period of that feud.

And what explains the greater likelihood of consanguinity among whites than among blacks (with the exception of ancient Egyptian royalty)? Yes - a new topic - but equally primative.
