The real hilarious one is when they say "X is a racist dog whistle". That means if you're hearing it, you're a racist you dimwit.

I've gotten decent at arguing from their point of view. See, they can hear the racist dog whistles, not because they're racist/dogs, but because they are highly trained and empathetic. They're basically superheroes, actually, always trying to protect others. Their superpowers let them hear things that other non-dogs/racists couldn't hear.

They've put in the emotional labor to be able to train these superpowers, because they care about others.

You fucking racist. /s
