I wondered where they were getting 'book burning' from. The only burning I know of from the past couple of years is when BLM or ANTIFA burned BIBLES during the riots.
A small number of parents protesting a small number of book they don't want their kids school library. The left is calling this a book burning. Every conservative on social media gets warnings, "fact" checks, temporary bans, permanent bans. Comments are deleted and the left cheers that on.
