That's what's obnoxious about that comment - it's completely unprovoked trolling, and yet it was heavily upvoted. Of course the first reply disagrees with it - If I go to a thread about a Ruby library and insult people for wanting to use Ruby, you'd expect the top reply to disagree. What you'd hope not to see is for that trolling comment to be overwhelmingly upvoted to the top, and for the community to be making excuses as to why in this instance it's ok.
If someone's not interested in some content, or disagrees with it, that's one thing, but to actively find, mock, and seek community support in ostracizing people who are interested in learning it because of that interest - I'd argue that's anti-intellectual by definition. But whatever you want to call it, it's, as the grandparent comment stated, a community problem. Sadly for the author of that comment, the HN community excuses that sort of behavior - it's just different from the wonderful folks in whatever language community they're used to.
