I explicitly said that these Rabbonim (who have no problem with an unmasked indoors crowded minyan ) are aware of the CDC guidelines. They just choose to ignore them. And their reasoning for ignoring them is extremely disturbing. I don’t think it’s unreasonable for even extremely intelligent people to believe patently false information. Especially these days when it’s very difficult for someone unaccustomed to modern media to know what to believe.
A shul where 90% of the people have had Covid, and the other 10% are spread out,
OK, hold your horses over here, this is a big change of pace. At no point did you say that we are talking about cases where there’s herd immunity. Because that’s a whole nother ball game. I do know that many shuls have rules about when people can take their masks off, based on when they had COVID or a vaccine. I’m not thrilled with it, but I’m not against it either. Was that what you were talking about this whole time?
My issue is most shuls do not have 90% infection rates. There was some thought that back in June of 2020 that COVID ran its course in frum communities and herd immunity was reached. That turned out to be wrong when Elul came and brought a horrific din v’cheshbon on many many people.
Furthermore, you say “90% had COVID”, but when they had COVID is extremely important. Within the last 3 months, fine. Six months ago? Not great, but OK. Earlier? Most people who had COVID lose their antibodies after six months. So a shul where everyone had a fever in Av and decided to unmask now has to go back to acting as if no one is immune.
