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.
When I was in high school it was always the English and social studies teachers pushing their communist ideology and the math and science teachers that had a very very slim chance of leaning right. You could tell the teachers that leaned right because they refused to talk about politics. The most you’d get was the rare eye roll or a scoff. You could tell the left wing teachers because they loved pushing their narrative often subtly but sometimes overtly. Our public school is garbage.
