Because it's a Big Question. Bigger than CRT, which I can pretty much guarantee no one here ever heard of a year ago.
Should politicians be able to dictate what is taught and what isn't? Here are some examples I'm pulling out of thin air:
Should they be able to prevent evolution from being taught in areas made uncomfortable by that?
Should they be able to prevent the teaching of Holocaust denialism?
Should they be able to prevent the teaching of the history of police brutality in the US?
Should they be able to prevent the teaching of Communism?
I can maybe see valid discussions on both sides of each of these. I can maybe also see the government getting involved in any of these as being Big Government/invasive government in a way that Republicans have traditionally (officially) opposed.
What's your take?
