I will defend the right for people to read characters as queer and to write m/m fanfic all day, every day.
But if you (seem to) need to justify erasing or dismissing female characters while doing so, or imply that m/m is the only way that fans can imagine a relationship of…
Probably been said already but there are few fandoms that have even one credible female character, never mind two to ship (afaik, please point me to any that do).
Others have ably risen to the call of providing oh-so-many examples of fandoms with a hefty roster of awesome female characters, which is great! But honestly, I have no time for or interest in proving that any female character or group thereof is credible. Who cares? This is FANDOM. We can write ANY STORY about ANY CHARACTER. Do you know how many characters I’ve read shipped with the Giant Squid? So many. SO. MANY.
I will go into fandoms and raid their fridges for ladies. I will raid their closets for ladies. I will raid their bars, their pep rallies, and their crime scenes for ladies. Maybe that’s not your MO. But please don’t try to claim your disinterest, laziness, or internalized misogyny means the internet has the burden of proof for convincing you that yes, there are fandoms with “credible” female characters out there. You don’t like stories about women? Fine. That’s not about fandom. That’s about you.
