By the way, Sam2’s stories reflect how every kefira, from notzrus and essenes to deformed, got started. Some malcontents got upset at an organized kehilla and because of some personal issue or misunderstanding, and they found an easier way out somewhere else that in the end took them away from Yiddishkeit.
I think the answer is 2 frum alternatives minimum, even if they’re run by the same kehilla or organization, in all but the smallest communities.
