Up until about six months ago, I saw it a lot from Haskell proponents here on HN. But with them, it was pretty much against everybody (except maybe users of F#).

Either the most obnoxious ones left, or they learned that this was not a productive approach. It's been refreshingly quiet lately...

But I disagree that there's a war every time Rust comes up, as a general thing. Many of the Rust proponents here are quite reasonable, willing to listen, willing to explain gently. (The conversation on the current article has gotten a bit out of hand, I'll admit.)
