I have never understood why anyone thinks the left burns books.

The last time I remember people prominently burning books in mainstream conciousness was the Nazis, including irreplacable knowledge like the IfS library by Magnus Hirschfeld.

The notion is so widespread among the right, Dave Rubin named his entire book after it. I have not seen anyone actually try to burn it, even though it is barely worth the paper it is printed on in my humble opinion (and the opinion of most critics).
