Same experience, but on the ubuntu forums more than a decade ago. Those people who can't get recognition IRL seek it online. It doesn't help that they socially awkward due to being ostracized IRL. So they have to spend a lot of time alone teaching themselves stuff / the hard way: through experience and by being belittled by other people who are a few years down the same experience.

They are just like Catholics: I had to suffer, so you do too. The lack of physical presence dehumanizes the interlocutor and makes it easier to be a dick and a compounding factor is one cannot punch somebody through a screen for being a twat.

The less fortunate discriminating against the even less fortunate because for once they have power. It's very human and as many things human, very detrimental.
