There are things you should not read when living among the humans: anything which reinforces what you think is contemptible about them.
I made the mistake of first reading about 'Unit 731' at my desk as a JET among the droids in a Japanese junior high school and thought: "Yeah, they'd do it to me."
I read Orwell's 'Animal Farm' in elementary (I have older brothers) and '1984' in high school, and have never trusted humans in the face of authority since. That is a fine thing.
And just recently, I have been reading Yevgeny Zamyatin's 'We' on the Tokyo train commute. Much too close to home. Think I need to start riding my bike to work again...
