Take the time to talk to your children about this. Our most vulnerable members of society are being indoctrinated even more than we are. They have no way to fight back, and they desperately need to hear simple truth. Not to take it back with them to school and argue, it's built to ignore and punish students who speak out. But to know for themselves that much of what they are hearing does not stand the test of fact or reason. Even if it comes from a teacher they really like. Teach them how to research and find what's true.
