It kind of feels like these "Legitimate gay men" are just sulking now that modern RPG's are finally actually having diversity rather than exclusively catering to their tastes.
I disagree. I think it became very clear that certain demographics sought to throw gay men under the bus at the first opportunity so that they can focus on pushing their niche fetishes into the mainstream, particularly those that are subversive.
My use of 'legitimate gay men' is to describe those who are not actually male or gay yet insist on speaking on our behalf. I will not go too deep into the matter here to avoid dragging the thread too far off topic but the term 'fujoshi' is relevant. I think it's strange that you're implying that many RPG's are 'catering to our tastes' when so few RPG's have ever made the conventionally attractive handsome men into romance options in the first place.
As an example, for as much as the Dragon Age games sought to be 'progressive', Alistair, Cullen and Sebastian were not romance options for male player characters.
Femboys are also very niche and bereft of masculinity. They tend to be what women obsessed with gay men tend to project onto hoping to engage in some twisted form of conversion therapy, whereas some gay men in denial like to convince themselves that if a guy is feminine or androgynous enough then it does not count as 'gay' which is in itself another form of erasure.
At any rate, we can simply agree to disagree - or take it to private messages, I suppose, if you genuinely want a debate on the subject.
