White nationalists are usually pretty immature so you can see that this comes from a schoolyard bullying tactic.

If you're the popular kid, just try fake tears and everyone will rush to your aid against the nerd who finally stood up to you (called you a jerk). Even teachers who get in on high school politics. I had one bully where his whole thing was "ironic homosexuality" where he would ironically flirt just to fuck with people. I called him a slur I deeply regret saying and then he fake whined that I was bullying him with this shit-eating grin on his face. Admittedly, I did get a much needed talk from the principal on why that slur was bad. However, it was also done in the context of 'two wrongs don't make a right' as if they didn't care that I was being bullied nor did they really want to hear my side of the story. Hell, why even get his side of the story at all?
