You're certainly right that this is an inflammatory topic with strong political and ideological overlap, and as the guidelines explain, we don't want flamewar here, and we don't want ideological or political battle. The site exists for intellectual curiosity, and those things aren't compatible. There's a great deal of established moderation practice around this, if anyone wants to read past explanations:

That doesn't automatically make a story like this off topic for HN. It depends on whether there's enough new information in a story to support a substantive discussion. In this case, the topic is not just "gender ideology", it's ongoing developments at universities and in the discourse at large. All of these are significant and interesting phenomena. For that reason I turned the flags off on this submission. That's also established moderation practice (https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...). It requires a judgment call, of course, and we don't always make the right calls—but not making any would be an even worse call.
Of course it's commenters' responsibility to stick to the side guidelines if posting in such a thread. That means curious, thoughtful conversation and respect toward other commenters (and other people generally). Flamewar, flamebait, snark, name-calling, personal attacks and so on are not ok. People sometimes think that just because a topic is inflammatory it means they get carte blanche to spew what they will (e.g. "if you don't want me to post like this then you shouldn't allow this thread in the first place"). I call that argument "the topic made me do it", and not only is it false, the opposite is true: commenters here are under a greater obligation in cases like this, as the site guidelines make clear: "Comments should get more thoughtful and substantive, not less, as a topic gets more divisive."
