What the fuck is this bitch talking about, isn't fandom like 50% Gaydens now? Fandom (aka female autism central) is literally ground zero for pooner creation.
I think she's right that people in fandom are fucking sick of them though. Pooners dominated fandom early, and people have had over a decade to to get sick of their shit. I still remember tentatively outing myself as TERF-adjacent to one of my friends who is heavily into fanfiction, and she immediately dove in and opened a floodgate of complaints about how she can't look for "male/male" fanfiction on AO3 anymore without the results getting clogged up with self-insert heterosexual stories in which pooners rewrite their favorite male characters as secret pooners. Like imagine you're looking to read something sexy about a male character you're attracted to, and on page 3 the author suddenly reveals "he" has a vagina lol
And I love the idea of that Redditor commenting on a fic suggesting the author "consult with a trans man." Yes, that's what everyone fanfic author likes to do when banging out a silly porn story, go "consult with" someone who will scold her in a little froggy voice.
