What are the sources for the gender science books? Never heard about that
one of if not the first public book burning the nazists performed was the burning of the archives of the institut für sexualwissenschaft (institute for sexual science) in berlin in 1933. the institute was a pioneering organisation for what we would today call lgbt people and from it sprung the first european gay rights movement during the weimar republic in between the world wars. the institute is remarkable for having performed some of the earliest hormone replacement treatments and the first sexual reassignment surgeries, and acted simultaneously as a research centre, a medical clinic, and as a social gathering space.
Doctor Magnus Hirschfeld (Z''L) who headed the institute was himself a remarkable individual, and is the person who first coined the word transsexual. virtually everyone connected to the institute were later either forced into exile, sentenced to concentration camps, or outright executed, and the nazists did their best to totally erase the movement that sprung from the institute from history.
^nazists, may they burn in the fire eternally, march on the institute and ransack its archives in preparation for the book burning.
