When I was a kid...
...I overheard one of my grandfathers (Pa) say to the other one (really a rare occurance for the two sides of my family to meet), say that we should ship all the niggers (pardon the quoted term) back to Africa and kill the ones that didn't want to go. The other grandfather (Grampy) laughed and nodded. This was (by way of background) during the first Watts riots.)
