What kind of books did the Nazis burn?

An expression employed by some neo-Nazis online to justify book burnings in Nazi Germany and to depict the Nazis as a positive force in human history. It is typically used with the implication that these book burnings, which often targeted queer literature and research materials, actually targeted pedophilic tomes. As such, the expression is sometimes used in conjunction alongside contemporary anti-2SLGBTQA+ tropes.
