This only happens because the problem is constantly ignored. Personally, it's clear to me that nearly every single time anyone tries to talk about *ism in tech it degrades into a meltdown of horrible and/or needlessly pedantic comments. So much so that the actual problem never gets addressed. No choice but to try again and again; focusing harder and harder on examples. I do notice though, over a wide enough range of time, the conversations do very slowly inch towards maturity. And just think, if not even HN can handle the topic... what hope is there for anywhere else? Seriously, if anyone knows of another online community of mature discussion comparable to HN I'd like to know. Right now, HN seems to be in a class of its own in regards to quality of comments.
The intelligent discoursers I know have all moved to communities like slatestarcodex, LessWrong, potentially-vile "neoreaction" sites (you can read Mencius Moldbug's writings for a primer), and other obscure parts of the Twitterverse. Your mileage may vary with any of these subcultures, and there is plenty of "toxic" content, but IMO the quality of discourse is vastly higher that what you'd expect on a typical Hacker News thread for anything not explicitly related to startups or programming.
"The X bias is Y, and from the data we'd expect a bias of Z, therefore the bias is D".
By calling it sexism, we make it a value judgement. By talking about bias, we remove judgement.
religionism.
People here (and everywhere google is a verb) ignorance is not only implied, but encouraged.
Personally, I found the post distasteful, though not enough so to merit a flag. I think its us-vs-them tone and cherry-picking of facts makes it very easy to dismiss outright. I think that does the women in our industry a disservice and exacerbates the problem.
