Don't just pull them out. This is an opportunity. Contact some of the other parents and make a big stink about this as a group. Force them to explain to a group of angry parents why they are forcing "divisive political propaganda" (specifically use those words) onto children. Force them to tell you whatever evil propaganda they're trying to push. Demand the teacher be fired. Demand a plan to from the administration to end any "anti-white racism" "communist propaganda" "anti-natal/homosexual propaganda" and whatever else from the school. You are in a perfect position to do some real good in the world. Don't squander it. This is how we start to fix the situation.
