Location, location, location! 
I work where I have to meet lots of people that are generally not happy to see me because I'm talking to them about problems their kids are having in class. Also, I have coworkers that I am friendly enough with (it makes the day more bearable) that I just sort of quietly listen to their terrible takes. Also, bookstores and other hangouts around here tend to have very opinionated people that don't hesitate to talk up strangers about their "ideas" (they want to sell you on some "hustle" or startup, both of which are abundant here).
Well, that and having a very chuddy biological family (in-laws are a lot better and that's where I go for the holidays now).
