I'm one of the few teachers in a TEXAS school that would probably be labeled right wing even though my economic philosophy aligns with the French philosopher Proudhon and the American heterodox economist Henry George.
Nearly half my district moved to devote an entire week to teaching Black Lives Matter. I had to go to the district meeting and point out that their proposed curriculum violated civil rights law to get the idea scrapped & I suspect I only succeeded because the state recently put my superintendent on alert for telling people to vote for politicians who oppose school choice.
You need to make sure your child's English & Social Studies teachers know at the start of the semester you will go ham on them if they try to be partisan. I teach science - physics - so I'm mostly immune from ever having to deal with controversial topics but I've had students try to get me to talk about politics and I refuse. I want to say I'm not the exception to the rule but that's increasingly not the case.
My friend is a teacher, she is a moderate Democrat but very into BLM and open borders. I've been sending her links of teachers using their platform to brainwash kids with their politics and it really opened her eyes. She says she now tries to introduce both sides to an issue and get kids to question the media narrative. So if you have teacher friends try to get them to at least be bipartisan.
