> Liberation literature is not in the same category as hate screeds.

Just as one man's Freedom Fighter is another's Terrorist, this really depends on perspective.

Das Kapital is kinda negative about capital holders, after all.

> You know what's evil - it's the stuff full of race hate and misogyny. There is no moral equivalence.

Is it all the stuff full of racial hatred and mistreatment of women? Because you're going to have a hell of a time banning the Torah, Bible and Koran - to say nothing of other religious texts.

Would a pamphlet against immigration be allowed?

Would a pamphlet against abortion be allowed?

Would a pamphlet against [Islam|Christianity| Judaism|Hinduism] be allowed?

Would a pamphlet against Israel be allowed?

Would a pamphlet against affirmative action be allowed?

It’s amazing how if you try to make a progressive political point here, you tend to get criticized. But when it comes time to judge the morality of things like racism or misogyny, suddenly it’s impossible to know the morality of any idea ever.

People aren't arguing that racism and misogyny are moral, they're arguing that if you allow any censorship at all, then someone must be appointed censor, and you may not agree with that someone. The only way to be sure that your ideas can be freely expressed is to allow everyone, no matter how immoral, to freely express their ideas.
