"The Nazis knew the secret of book-burning was to build a pyre with a whole bunch of volumes, as with the library of Magnus Hirschfeld’s Institut für Sexualwissenschaft incinerated in Berlin for its scientific research on sex. (Spooky! Rowling’s views on biological sex — ie that it exists — are controversial too. Guys, it’s an omen!)"
Interesting choice for an example - The Institut für Sexualwissenschaft performed some of the first SRS procedures. They also coined the term 'transexualism', employed trans staff members and lobbied the police to stop harassing GNC people. Small wonder the Nazis hated them.
(Naturally, the Nazis didn't burn the staff or patient records...)
Such an apt and tasteful comparison for a poor, beleaguered billionaire pulp fiction author whose burnt books have already been paid for!
