There are reasons to do with the history of this particular literary form, as well. It may be that, for a number of fair reasons, women are allowed to denigrate men in print, but not the other way around. “I think some of the things I get away with saying about men would seem a bit gross from guys, because of the obvious power imbalance,” Annie Lord, British Vogue’s dating columnist, told me. Women can write about dating because on a heterosexual date, society generally accepts that women are the underdogs.

Perhaps the presumption that the same privileges equally translate to different contexts plays a part. I don't see any "fair reasons" listed here. I see a group that is allowed to say negative things about one, and another that is shut down for the same thing (but that they have fair reasons to be allowed to). Maybe nobody should be denigrating anyone and it is just, in itself, unfair to denigrate others?

On any dating advise site/community I don't exactly see women as the "underdogs" with regard to support and who is 'right' in any given situation. The first examples that come to mind are reddits dating advice and "AITA" subs where I've seen more than enough examples of the old "switching genders completely changed people's opinions" posts to not feel comfortable there.
