I don't think anyone is saying what happened was acceptable.
What posters like myself and others are trying to explain is why so many people would have been "willing" to break the rules.
Even devout Catholics like my MIL engage quite freely outside of her religious community. Her religion, whilst very important to her has not precluded wider life experiences.
What is hard to understand for many people is that for the Ultra Orthodox there is no distinction between their religion, their community, their rituals and their life.
Their community, religion and it's rituals are their life and at the heart of it is an incredibly strong sense of communality.
Every day/week/month is "centred" around these communal activities. There is nothing else - no TV, internet etc for the vast majority. As pp's have explained, shops, schools and most services are provide within the community.
Not being able to participate is not the same as someone like myself lamenting not being able to go to the gym or my MIL not being able to go to mass.
It's akin to having the meaning of your existence ripped away and in that context it is why some UOJ's would take their chances with the virus rather than not.
Again to be clear I'm not saying this was ok, but I think the are a lot of posters who really don't understand the world members of these communities live in because it is so very, very different to ours.
