The schools are going to push CRT (Communist Revolution Theology) because they get extra money from the Feds by doing so. Who are the schools going to listen to? The angry parents or the people paying them? The States should pass a law that for every dollar of Federal money a school takes in the State will cut funding to that school by twice that amount.
The Constitution clearly did not intend for the Federal Government to run our schools. Such a law would go a long ways towards getting them out of the way.
