Yes, I agree it doesn't persuade anyone to call them names. I don't excuse that behavior. But again, it isn't wrong to say that the GOP uses racism to this day to win votes.
Do you believe that the Democratic party doesn't use racist rhetoric? I don't even want to make this an us vs them whataboutism.
Now, in response to that you sort of just wave around and claim all parties use racism. But that's not actually true is it, there is no similar concerted strategy on the Democratic side to stir up racism to drive votes- and this is born out in the numbers where one party has a very out of the norm demographic appeal.
That's still not an actual response to what I posted, it is what we all know to be whataboutism. Nobody wins by playing the "they do it, too, but better" card. It just makes the losing party look incompetent and a little evil.
