Daas Yochid…. truth be told… and others…
I hardly think the din of a mosair applies to one who is trying to keep Yidden from endangering their own lives and the lives of others, AND/or making a chilul HaSh-m!
It is odd that so many bochrim choose to be “machmirim” when it comes to the issue of drinking on Purim.
How many times have we all seen inebriated bochrim throwing up on the streets, or wandering into the streets (into traffic) or just generally “making a scene” on the streets on Purim that is truly a chilul HaSh-m?!?
If someone can prevent this, that is NOT “mosair”, it’s a mitzvah!
