I've noticed a very big difference between comments about rust on general programming sites like here and /r/programming and comments in rust specific spaces. I find people in rust-centric spaces to be calm, reasonable, kind and pragmatic. Some of the worst rust evangelism I've seen comes from posters who I'm not even sure have written serious amount of it. I agree with you that it can be really off-putting. From my perspective what you are seeing could be more of a comment on some of the know-it-all dilettante types who fawn over trendy tech in comment sections than the rust community itself. I've always had great experiences when reaching out for help in discords, user forums or other spaces. I've seen similar patterns with other trendy technologies in the past too.
