I absolutely agree. Being stupid and insulting is not good, both in general and for the language. Not acknowledging other languages' successes means that we have blind spots for improvements, not to mention things like you've commented all over this thread.

As others have said, I think this is more of an HN issue than anything else; you won't see this kind of discourse in Rust-centric spaces. I know that's not super helpful, but I'm not a HN moderator, so...
