There's already a stereotype that Rust people will just carpet bomb any discussion with aggressively promoting Rust, people expect it to happen at this point and it just annoys people.

So I think it probably meets the threshold of "toxic", but more importantly - it's not effective. Everyone and their dog has already heard of Rust, aggressive proselytising is not going to help drive Rust adoption, it's just pissing people off

it's toxic because of how it sometimes materializes:

- predictable

- incessant

- with belittling/reductionist/arrogant/elitist/combative phrasings

- handwaving rust shortcomings and tradeoffs

I think they are mostly just idealists. Found a perfect programming language that allows them to claim that everything else is wrong, and rust can solve every problem under the sun.
