[Cthulhu_]

It's not related to the job per se though, it's more about personality / character (and there was another word but I forgot, er, words); people in IT and software development tend to lean more towards the introvert spectrum, the socially awkward, the physically less fit, etc. That + choosing to spend more time at a computer instead of interacting with people IRL (doesn't have to be that much even) causes a gap in development.

Of course, #NotAllDevelopers; I feel like I'm somewhere in between (but in part because of some effort on my own), and my company has quite a few developers that lean towards extroversion.

The problem in this case is that when someone steps upon a soapbox on the internet, they reach an audience of potentially millions; even if 0.00001% is a bit er, maladjusted, that's still enough for a few people to start making that kind of comment or show that kind of behaviour. Even if 99% of people were well-behaved, the 1% could still cause shit. And that's not easy to deal with.
