The teachers are really not the problem... it's the State. Teachers actually have very little say about even their own classroom behavior. In the states, the teacher's union controls the dept of education. They are all Cultural Marxists bent on indoctrinating children, not teaching them. Teachers are generally not equipped to handle children. I had the same problem you did- the teacher told me my son couldn't come back to class unless I medicated him... I homeschooled them all after that!
