>accuses him of misogyny
>he says he's a fag in the post
This is, of course, absolutely bullshit, most gay men don't hate women, they love their sisters and moms and aunts and nieces and whatever. Its a false accusation to try and get leverage over fags, with very limited success, because that or accusations of racism are the only options they have.
To be fair, gay men can be sexist and misogynist. They're generally not, but they can be.
But to SJW-types like the mods here, and at ResetEra, and at Something Awful, it's not really about being misogynists. It's disagreeing with them. A woman disagrees with them? Internalised misogyny, or they get accused of being a 'pick-me' girl. Black women - and by black, it's inevitably either someone who's mixed-race, like Koala's March from SA, or who is from a well-off, non-projects family, like Nepenthe from RE - and their lickspittles especially can go nuts with accusations of misogynoir, a twofer that gets all white folks and all male PoCs; sexuality isn't even involved. This also colours Asians, Latinos and Jewish people, because BIPOC was invented for a reason and it wasn't to promote unity.
You'll notice, of course, that troons don't get accused of misogyny, because to do so is a TERF dog-whistle or some such nonsense. Also other black women usually get a (public) pass, because in these spaces there's rarely more than one - at least, one that's willing to make it their entire identity, let alone get into a position of insignificant power like unpaid moderator for a lunatic-progressive forum. Undoubtedly, they make sure to keep tight on their fiefdom and prevent any other non-white women reach their level.
RPGNet, I believe, doesn't even have pretend black women as mods, so they have a vacancy - but troons generally aren't that fond of black women either, because they're a challenge for their spot on the oppressive stack and are less inclined to put up with their bullshit. Also, while they'd say it's that women and PoCs aren't welcomed into nerd spaces, simple fact is that fewer black women are interested, in percentage or basic number, in the kind of things these forums were originally created to talk about.
Tl;dr: Gay men aren't really being called out for being misogynist, though some can be. They're being called out for disagreeing by identitarians who have no interest in correctly identifying why someone said something they disagree with, just that they did and must be put in their place. As
@JohnDoe points out, there's some women 'activists' who can't stand that they don't have any typical leverage over gay men, and also that their go-to insults about men they disagree with, calling them incels and the like, have no effect on them. Unsurprisingly, they often get quite homophobic in response.
