The most salient thing about Dahlia's posts is the hypocrisy. The total inability to apply the same standards to her own behavior that she demands of other people.
She posts a thread whose sub-text is that the Holocaust was fabricated. She then accuses people of trying to shut her down. When that doesn't happen, she then tries to shut them down by shaming the moderators into erasing the posts of people who say she is anti-semitic. What a moral inversion it would be to allow her to post anti-semitic propaganda but then demand people call it something else. Who the hell would go for that?
Oh yes, she's not denying the Holocaust. What she's really doing is questioning why so many Jews have a casualty number on their brains in advance of it and are using the word holocaust before the Holocaust. But there's no conclusion to be drawn from that.
Whatever happened happened. We can't say what happened, but something happened. Or nothing happened. But the nothing that happened sure did happen. Or it could have been something that happened, in which case it's obvious that it happened to happen too.
