“Why not an alternative Public school system?”
Here in NC, there is a huge surge in home schooling, so much so that the state cannot keep up with the notices of intent. I would hope that parents who do keep their kids in public school start paying close attention to the curriculum, and ask their kids every day what they learned. They should be a bit probing; did they talk about BLM, about LGBT, did they try to make you feel bad because you are white, etc. and then come down on the teachers when they start this crap.
Coming down on teachers wont do any good. You have to go after the school districts and the state board of education establishing the curriculum.
