“Then are you equating anti-vaxxers with Lev Tahor?”
I wouldn’t have a problem making that comparison, yes. I’ve already called the anti-vaxxers a cult on another thread, so I’m way ahead of you on that. The main difference here is that the anti-vaxxers don’t seem to have a central authority like Lev Tahor and Chabad. It’s not like you were saying Chabad was identical to anti-vaxxers on the other thread, you were just pointing out a striking similarity, same thing here. He’s pointing out that they’re both personality cults, not evaluating/comparing levels of “evil.”
On the other thread he mentions Rabbi Berland’s followers as another example. There is no weight to the claim that he’s speaking of all Chassidim. The fact that he worded in the plural instead of just making a direct analogy to Chabad, I believe, had more to do with being tactful/getting through moderation than with making a blanket accusation.
