Okay, here it is! He doesn't get to just name people whatever he wants to call them. When straight white men gave themselves the power to do that, all they managed to accomplish was showing their utter contempt for everyone who wasn't them.

They horribly abused the privilege they gave themselves to name people as they pleased, and I'm not just talking about PoC, (because no one knows just how many horrible slurs there are just to refer to "women"!)

It costs your Grandpa absolutely nothing at all to call any group of people whatever they tell him to call them! Anything else is just blatant disrespect.
