I think they like it when the students don’t care about their history. Ignorant, fat, immoral, and lazy: the tyrants dream subject.
The teachers are a mixed bag; but I agree, the vast majority are flaming liberal idiots. I was surprised to learn that my daughter's "science" teacher (10th grade) thinks man made global warming is a junk science hoax.
I don't mean that to be an endorsement of the public education system, or that I don't agree with the premise that schools are, by and large, indoctrination camps for liberal orthodoxy. I'm just relaying a personal observation that there are at least a few teachers swimming against the current.
History is now Social Studies.
