More about the synagogues, for example here in Shiloh, there are large synagogues that were built to normally seat well over a hundred worshipers comfortably, and there are others that utilize small prefabricated shelters. In the large synagogues it's certainly easy to arrange safe seating for dozens of worshipers keeping their required distance. On the other hand the smaller building may not even be large enough for even a minyan quorum of ten, if they carefully follow social distancing regulations.
The government's "one size fits all" ruling is idiotic and counter-productive. There is no other way to put it.
|A synagogue as large as the main synagogue in Shiloh, Mishkan Tabernacle Synagogue, certainly has room for over 50 worshipers to sit safely, according to social distancing and another 20 or more upstairs in the Ezrat Nashim, Women's Section.|
