The Nazis were leftist degenerates in their own right (of you’ll pardon the pun; see the shit Josef Goebbels got up to). They fought and murdered everyone who stood in the way of their power, left or right. Just ask Hitler’s predecessor as Kanzler.

And they burned a lot more than Commie or sex change books. Indeed during the Molotov-Ribbentrop Pact they even burned reports of the Holodomor.
