He doesn't. He cares what YOUR ancestors did.
He just doesn't want to be called out in his hipocrisy.
If he cares about what my ancestors did then he can pay me reparations for the half dozen direct ancestors who fought for the union cause. My 3rd GGF and his two brothers came from a Quaker family and were abolitionist. A month after Sumpter, they all three enlisted in Wheeling in the 1st Virginia Infantry (Now West VA, so it was a union unit). They served for the duration
So, Ben, you don’t want anyone to know about your slave-holding, secessionist traitor, DEMOCRAT ancestors? Too bad, but at least you uphold their traditions of being democrat party traitor, scumbag, bastards.
