That may well be the case. HN has a community of zealots for just about any programming or tech related thing (pro-Apple, anti-PHP, anti-C++, pro-functional, pro-javascript, you name it). That doesn't mean criticism (or support) automatically comes from a place of zealotry. In this particular case the parent comment in this thread didn't read at all like religious zealotry against mongoDB to me. I suppose one might infer from it notion of a default assumption that developers are all zealots about their particular technology choices. I'm not sure such an assumption itself is terribly bad to have, honestly. Sometimes I think that if my only insight into the world of technology came from startup job postings and HN, I ought to be forgiven for thinking that the entire industry is a kind of elaborate and humorous play on role-playing game mechanics ("Ruby Dev" <==> "Developer/Ruby" class/skill combo), which are notorious for producing fanatical devotees of one combination or another.
