I don't see any evidence that he violated the rules; he described Coraline Ada Ehmke as a "toxic loonytoon" as part of his opposition to her ethical beliefs. Whether or not he is correct about that, I don't see how it's a violation of the rules to say so — it's not as if he used a slur against women, white people, or transgender people. Even when he railed against "Marxism" (it's not clear to me whether Ehmke is a Marxist, but certainly some of her supporters are) he didn't use slurs like "commie" or "tankie", despite the bitter hatred of Marxism that his life is oriented around.
