Where do you have these interactions? I'm frequently on the Rust forums and the few times I have seen something toxic brewing, someone has always stepped in to politely ask the fanbois (yes, they exist) to stop.
Reddit is so full of trolls that I've mostly stopped contributing, except in a few subreddits that are properly moderated.
Sorry you experienced that :/
For what it's worth, I don't think I've seen anybody from the core Rust community on /r/rust.
It's even worse when really senior figures in a community are also the source of the toxicity.
That said, I have not interacted with the Rust community and cannot make any comments in that regard. Language is pretty nice though.
I'll leave with this: I'm a super introvert who works from home, so I took my difficulties as possibly me needing to take a break.
I actually track Rust quite closely since there's a lot of neat and innovative work coming out of it, and I hope to join the community since it seems like many have had a lot more positive of an experience.
