So the thing is this is mostly a matter of which texts your school purchases. Since the leader in purchasing (at least when I checked a few years back) was Texas’ board, publishers tend to prioritize what they require. There are usually alternatives and teachers have (or had?) some autonomy on this, but many are pretty neutral because why would you go out of your way to research these things?

Anyway, currently we also have an abundance of book banning and the politicalizarion of the PTA so it’s probably even worse right now. Also, Trail of Tears is like the token indigenous atrocity story, kind of like how a text will have 3 paragraphs on MLK to cover all of the civil rights movement.
