aposhiteyid, here in US we had such lockdowns for very short time period early on.
I saw R Heineman (Baltimore) being asked whether several families can stand in their backyards and daven together. This would be within rules and the questioner was concerned whether this will constitute “one minyan”. The Rov answered that a passerby may not see a difference between standing on one yard or many yards, he’ll just see Jews doing something. As the result, he opined, when there will be a lack of ventilators, someone might decide not to give it to the Jewish person.
Rov was using accumulated century of Jewish wisdom of how non-Jews may be suspicious of us. You are looking at the sunny side of a modern society, expecting everyone to look favorably at you. It might be so for a moment – until it is not.
