I once heard a radio DJ say that it’s just a given that everyone who lives in our state watches basketball to some degree. I mean, I did…..decades ago as a kid when my dad basically forced me to as “father-son bonding”, I was bored as shit every game.
I was also told by a co-worker that even though I don’t like country music with only a few rare exceptions (90’s Garth Brooks mainly) that I’m definitely going to like it eventually because that’s just how people who live here turn out according to him. I decided to spare him the info that currently I mostly listen to hip-hop, rap, and J-pop, probably would have broken him mentally.
Like I was born and grew up in a state/area, didn’t mean I joined a goddamn hivemind cult. People who throw out these sorts of absolutes are just obnoxious.
So yeah, OP, you’re not wrong for finding these sorts of generalizations annoying.
