I don't think there's a difference in how willing people are to do it (e.g. I've definitely seen people who haven't touched Rust have strong opinions about it).

I don't think there's a difference in how willing people are to do it (e.g. I've definitely seen people who haven't touched Rust have strong opinions about it). However with security it's very easy to accidentally say something someone can show is clearly and unequivocally wrong, with decades of research in tow. A lot of other technical opinions on HN are ultimately up for debate. You see the same thing with physics and mathematics here fairly often: every time quantum computing comes up some people ask some good questions, and then a bunch of people give them confident and embarrassingly wrong answers. Finally others (including me sometimes) shout them down. It's just less noticeable because those subjects are rare here compared to information security; tptacek and others are constantly fighting the good fight.
