Was planning to send a similar problem, in particular about people who HAVE to make sure people know that they ship this M/F pair as Fdom and that she totally pegs. And I don't mean people who just mentions their preference, you know the ones I'm talking about.
Sigh. That one again. Don't get me wrong, there are definitely people who got weirdly overcompensating over fandoms biphobia/transphobia and general hatred for m/f ships. However: You do realize that bisexuals dating bisexuals, trans people dating trans people and even women who peg their boyfriend do exist in real life, and sometimes just want to see themselves in a story, right?
And yeah, you can say "not the one ones who just like it, the ones who posture" about it all you want... but there are a lot of people for whom every single instance of these people existing, even just projecting on fictional characters, is posturing. And it might be interesting to explore why they get accusations of posturing but wlw and mlm ships and even more traditional m/f ships rarely get these accusations
