Thinking about this some more, just who would they expect to pay the cost for reparations?
Obviously "the government."
But, the people demanding reparations would, in part, be paying for their own reparations payments. And a LOT of people whose ancestors (including mine) never had a thing to do with slavery, and even actively fought against it, would be forced to pay "damages" for something they never had a hand in in the first place.
I think that point alone would be worth opposing it, if necessary, up through the Supreme Court.
