Every parent should tell their children to start recording CRT and race teachings in class. I know that students are not supposed to have their phones out and it could get them ISS or even kicked out, but isn't it worth it to have your children protected from pathological liars and race-crazies? If the teacher doesn't do anything wrong, so be it, but if they do, you have it in recorded form as proof. So, you might end up having to home school your kids or put them in a private school, but that's the price you pay for doing what is right.
