Yeah, when they teach about book burnings they never mention that fact. It also serves as a reminder that trans people are not just a modern phenomenon. The Nazis’ reasons for targeting trans people then are the same as right-wingers today, they look for a small, marginalized group and seize on existing prejudice to sow division and divide and conquer. The Nazis claimed trans people were a Jewish plot to weaken and destroy the Ayran race, and you can still see echos of that in some right-wing rhetoric today.
