Scotland here. We don’t boil water before use.
I have family down in North West England that do have to do this, though. They live in an area where there is a thin layer of soil and a lot of clay. The water isn’t particularly hard but it also doesn’t taste very nice if you don’t boil it first.
I’ve always though that being an incel would be far too easy to get into. Back when I was a young, (even more) socially anxious and depressed teenager, I could see myself definitely agreeing with some of their world views. Thankfully I finally took some responsibility for my own issues, much like you have done, but it’s absolutely wild to me that I almost found myself identifying as one of them.
