i understand you are concerned, my question is why are we scrutinizing minaynim more than say grocery shops, hardware stores, office space, airplanes, or a congress testimony?
Why would we lift any restrictions at all? maybe because some people have had Covid19 and tested for antibodies and are resuming life to some degree and that includes davaning with a minyan with SD.
How long are we going to make the what about x argument? Don’t go to groceries or hardware stores either. Rabbis don’t control stores. They can pasken about minyanim. People need food they go to grocery. Rabbi-Dr Glatt has said numerous times that visits to the groceries should be only when needed, very quick and only one person per family. It’s is preferable to get things delivered.
Haven’t the studies showed that only 20% of the population may have anti-bodies? So screw the other 80%? If you think those 80% will be smart enough to stay away from minyanim and Shuls by themselves - after reading this forum and the other “frum” site I am fairly confident in saying they are not.
So what happens? We have more sickness and more deaths. Why? Because we never learn our lesson.
My fatherinlaws shul in Flatbush was open a full two weeks longer than my shul in five towns. So many people got sick and there were deaths from that shul. I told him what is wrong with your shul just shut it. The reply was “the Rav believes in the koach of teffilah betizibur”. I heard they are making plans to reopen their shul very soon.
So this is why we can’t have minyanim yet. People have a very short-term memory and in general seem to be extremely foolish about this. As sad as it is to say, we cannot leave people to their own devices.
