That's been my main gripe with the site since I joined years ago, and since coming back from hiatus: The general attitude of conversations is often "I disagree with you, and you're dumb for thinking this way." The empirical content of these disagreements is always fantastic (which is a big part of why I enjoy the site), but it's usually interspersed with personal insults and other immature comments. We also have the tendency to submit a singular vision of what's true, which is oftentimes epistemologically dishonest. It sucks that even writing a comment like this, I'm trying to word things very carefully because I know I'm inviting criticism by having an opinion. It sucks that people leave this site forever because they don't have the energy to deal with a disagreement that's full of language designed to humiliate them.
