That's definitely a good point. My comment was a kneejerk reaction to assertions like "Hacker News is a cesspool." I agree that we should address anything that makes people feel unwelcome or uncomfortable because of who they are.
And yet your original comment didn't say that, it just immediately went #notallmen. If you admit there's a problem, start with that. If you must start a tone fight, do it as an aside.
The community doesn't have to be 100% racist or sexist for there to be a problem. These are all from the same threads as the original article:
