school teaches blatant propaganda all the time.
I had to fight my high school history teacher about how the Germans in WWI were not some all-evil empire. Also American imperialism, the treatment of native Americans, Vietnam was not a glorious war for the US, etc. lots of 1960s ideas being preached still
Lots of what you learn in school is to reinforce a certain standpoint. I would not say they're 'reeducation camps', that's wayyy too 1984, but the idea has merit.
