I've sperged on this a lot in the Pooner Zoo and Antifujo threads, but the problem of girls latching onto gay ships goes much deeper than you might think. Female heterosexuality is still the more repressed of the two, and the sight of a woman next to a man makes many young girls uncomfortable due to living in a world of modern sexism. Japan is very dismissive and objectifying towards its female residents, so it's no wonder why it boomed especially big there.
This video lists the main reasons for fujoshi's obsession with BL, and they all relate to the idea that the female body is problematic compared to a male one. Even in fantasy land, the fear of pregnancy lingers in their minds, for example. So they distance men from women as much as possible in their romances, and as a result end up relating and "identifying" with gay couples only. That's how the fujo-to-pooner/"lesbian" pipeline works.
You are not kidding. I scrolled through the comments and actually got MATI reading some of them.
Projecting onto males as their female bodies disgust them:

They're all "aroaces" aka sex repulsed women writing and consuming pornography for women:

"It makes me feel equal to a man"

Those same plots you hate in straight stories are there in the gay ones, you retard. I can attest with receipts. You'll complain about the male gaze and yet erase women from all relationships because you deem males as the default love and sex.
"They allow more freedom in storytelling"
"Self actualized characters"
Aka women are not people. You are not playing with gender if both of your characters are male.

She doesn't like being treated as arm candy, but if it involves a bottom she's good:

The power imbalances drive this one nuts:

Worried about sexism? The solution is just to erase all women:

"The books I read have to be gay because the sexism is so bad"
But excluding all women is good because...?
"I only like girl boss and malewife"
"I'm personally a dominant person" suuuuure you are.

She hates power imbalances, yet resonates with another power imbalance provided she's the top.
And the winner: femboys as a third gender, because men are better at being women than women:

Sometimes the worst enemy of women is other women. The admission that they like male characters more as the are seen as full people and given full human characteristics isn't fighting the patriarchy, it's admitting that men are superior.
Dudes rock, even in female porn.
