I grew up in a very conservative Catholic community. Imagine a group where JD Vance and Harrison Butker would be considered mild. If a new person didn't show up in the right kind of clothes and faux humility, people would make a snap judgement and start gossiping. If the new person were wealthy or had a lot of children (8+) or were in a medical field, they would probably be ok. The single parent mom with two kids who dared to send one to public school for better STEM classes? Lol, she had no chance.
There was a "welcome wagon" type group who were supposed to invite new people to coffee and doughnuts with the congregation in the basement after services. I watched the one invite one family and offer a handshake, visibly retracted the hand to skip over Single Mom, and then extend an invitation to the next family. Ice cold.
There has got to be a term for the particular type of ... restlessness(?) that movies like VVitch and Hereditary inflict. It's not exactly horror, but a distinct discomfort that I can't quite name. Talk To Me also got close for me but not as far as Hereditary.
