Actually, I just want to requote select bits of that with emphases, because it becomes more abhorrent a statement the more I reread it:
People (and once again, let me emphasize that for hate crime laws that means people who historically were absolutely brutalized and often still suffer oppression today) must be sacrificed - to an idea. Not an actual practice, because** there’s no place where free speech is absolute**. But the idea of free speech, that is the Moloch into which we must feed actual people - our gays, our PoCs, our Jews, our disabled, all our oppressed.
All so some Nazis can get to deny the Holocaust with impunity.
