Every community has these assholes. In my experience, the Rust user base is nothing but polite, understanding and pragmatic. There's no smugness, explicit or implied. The Rust lore is just a joke that's getting less funny every day someone takes it seriously.
Yet, almost every Rust thread here serves as a evidence that your experience doesn't reflect reality.
I feel like it's far easier to find more zealously anti-Rust people than zealously pro-Rust people - hating Rust has almost turned into a meme.
