/r/programming is not an anomaly. My experience is that programming-related discussion boards everywhere are like this, almost from day one. The rampant tribalism and insistence one groupthink is incredibly strong, to the point where even typos can cause a relentless dogpile and accusations that said person "has clearly never written real software in their life." You simply cannot make even one mistake, no matter how minor.

Consequently, I haven't discussed programming on an open forum in over a decade, because I've never found a single programming forum that wasn't openly toxic in this way.

Frankly, that's my perception of HN, too. Try telling someone here that running your own email server is easy, for example, and then prepare to fend off the throngs of people clamoring to be the first to tell you that email is hard (tm), and only fastmail can save us from Google's dragnet, oh also email is deprecated and we should just use signal or some other proprietary walled garden.

And the irony that your comment gets downvoted for pointing out that HN too suffers from a tribalist mentality about certain things (it does)... All these sharp minds don't like to be reminded of their own strange little obsessions and failings as human beings.

Well, I guess there are different levels of expectations on what easy means. letsencrypt with dovecot and postfix is the definition of complex legacy, but in times where everything is spam that didn't come from domains with dmarc et all... there might be people that think of "what email server is" differently than you.

Could that be, because so much of programming is a group activity (understanding, maintaining, and evolving other people’s code), and thus actually benefits (in an evolutionary sense) from simplistic group think more than from innovation and perfection?

I'd chalk this one up to folks with enough time to endlessly post on Reddit not spending those hours building and maintaining software.
