I’ve seen people accosted in public for wearing conservative political t-shirts or hats on multiple occasions in Chicago. It was pretty frothing there from 2016 to 2020, and I’m not even a conservative.
Wow, never seen it in a city, and I've been around plenty. You see the absolute craziest things in cities and nobody even notices - it's part of the culture. It's a running joke.
I notice people yelling at strangers (there’s also a whole bunch of videos of people being jumped for wearing clothes that signal conservativism, but I haven’t seen that up close), but a much less extreme example is just gender stuff: my wife and I have a pretty traditional division of labor (by happenstance, not design, although it doesn’t matter for the purposes of this discussion) and we get some funny looks/remarks from a lot of people. It would be simpler if I were passionate about cooking and my wife was the breadwinner and finance manager, but we still have it better than people who are actually conservative.
