ZD, there are plenty of regular, frum shuls, of many types. It’s not that they haven’t been exposed to normative Judaism; they have rejected it. In fact, two of the shuls Avram mentioned used to be frum.
Syag, please link, but either way, that’s not his main argument. If you want to discuss his secondary arguments, perhaps you want to comment on his opinion that the Moetzes issued this kol korei not l’shem shomayim, but as a diversion from its own issues.
I disagree strongly with your implied opinion that we don’t need to reject this movement for our own sakes, and for the sake of the future.
