RebE > someone who is vaccunated should not have to wear a mask when the other person has the optiion to vaccinate
coffee > This calls for a kiddush
No, this calls for retrospection. Coffee, I understand RebE that he does not want to bother protect someone who does not care about himself. I.e. as in a mitzva to help the animal “with the owner”, i.e. only when the owner participates. So, RebE writes off these people from “reecha” .. nothing to celebrate … I would not go that far – not greeting is ok, but not care at all …
By the way, as I just quoted in another thread, Israeli research showed that out of 40 vaccinated health workers who got infected, ALL were infected by unvaccinated. So, unvaxed remain a threat to others.
