As a conservative: What causes it is that you basically have to retreat completely from society to avoid seeing opposing views.
I'd have to avoid all the late night shows, most newspapers and TV news stations, and most social media. It doesn't take long to get inoculated. As a left-leaning person, it's much easier to see almost exclusively your own ideas being reinforced.
> There seems to be an idea that the things that offend them are, like, “naturally” abhorrent, so it’s not offense so much as, like... digust in satanic things, virtue in “common sense”, etc. There’s a whole language to talk about things that carefully avoids the concept of “being offended”.
I'm sure that's a debate to be had--but to apply most applicably to this discussion, I mean "sufficiently offended to leave a website, stop watching a video, block something, report something, or otherwise feel like you've had a negative experience." The kind of things social media algorithms will pick up on.
