I've read Mein Kampf, The Communist Manifesto, The Turner Diaries, and The Cornerstone Speech. I've watched Triumph of the Will, and The Eternal Jew. I read Andrew Anglin, Jared Taylor, National Vanguard, and the national-socialist propaganda that pours out of Twitter on a daily basis.
We read difficult, horrifying things in order to understand them. We read them in order to understand the minds that created them, and to learn how horrific ideologies might be diminished, defeated, and prevented from taking root in our society.
Our universities must never punish people for reading terrible things.
Also worth noting is the reality that a person's ability to accurately assess reality is in far graver danger from watching Tucker Carlson nightly than it is from reading a poorly written autobiography like Mein Kampf.
