metafandom I found an entry on
Queer Character Tags on AO3, Current and Future. I found the amount of trans-related tags intriguing, so I clicked around a bit and stumbled over this Harry Potter fic with the tag "trans" and went "oh, my one and only fandom! Gotta check this out!" And you know what? I actually really enjoyed it.
