Mrs Syag,
thanks for clarifying. I think we have a profound disagreement here – which questions are important and, further, where chumrot are applicable.
It would be a bad pun to say that “nobody died” because I said 1 kaddish instead of 3. I obviously showed chesed to freezing people. The Rav did not correct me. so, how bad it could be.
You just can’t say the same about people not wearing masks, especially in the communities where so many older people died. “no shortage” of doctors is a strange reference. This illustrates that you are willing to approach this question in a much lighter way than question of liturgy. (Overwhelming majority of doctors tell people to wear masks. Re: rabbis, I quoted a psak above that one should not ask such Rabbis shailos, so it is a catch-22 here).
