Truth is the primary purpose of our schools is to be the primary government indoctrination tool. I still remember the asinine "sociology" and "history" classes taught by a socialist feminist teacher. I was literally forced to agree with marxist nonsense in her tests or fail the class. It was so blatant as to be comical. This also shows up in our SAT equivalent as rules about "respecting human rights". Imagine a question about proper terms for trangender people suddenly showing up in the middle of a mathematics test and you having to pick the "correct" answer. Wrote anything even remotely controversial in your essay? You're not making it into any university.

I have videos of primary school teachers teaching children to sing worker's party songs. I wish I was making this up.
