Slightly off topicYo. Like half my characters are trans, lol.

I think it's just harder to pick trans characters out among strangers, so they seem less populous because they're less visible.

I think there's usually nothing outwardly about them that says "this character is trans" - like, visibly, externally, my male characters use male models (whether they're trans or cis), and my female characters use female models (whether they're trans or cis). From my lineup, it's not possible to pick out who's cis and who's trans just by looking at them (except Shuu, who uses they/them pronouns, lol).

Even people who do use female models to represent male characters and vice-versa (which is legit, btw) - it's not possible to tell if the character is actually trans, or just an effeminate/butch cis person, if the player just wanted the gender-locked outfits from the other sex, etc; until the player tells you in some fashion (be it IC or OOC).

And it's not like "hey so what are your genitals like" or "so, like, did your parents ever think you were a different gender than you actually ended up being" or "have you ever used a fantasia/had major reconstructive surgery" is a topic that comes up in casual public conversation the same way "so are you seeing anyone" is.

There's opportunities for homosexuality, bisexuality, and so on to come up in small-talk, in first time meetings, to be made obvious by the fact of cuddling or kissing a same-gender partner in public - whereas a character being transgender is usually something you'll only learn once you've known them for a while. So you've probably run into some trans characters; you just don't know it. :)

[connie voice] Or that's my interpretation, anyway.
