AFAIK there are more trans women than trans men In General, like 2:1-ish, also a lot of the forums in which you play mafia (broadly the sites on which mafia is played in general but there are some exceptions) are, like… sites which will naturally appeal to young closeted trans girls, stuff that “boys” aren’t explicitly pushed away from/will still know exists but isn’t explicitly masculine
If you want to play mafia with a bunch of trans men then you can play on Flight Rising where the ratio is completely skewed in the other direction I genuinely can’t think of any trans women I’ve met through Flight Rising? I’m def missing somebody but the ratio is INSANE
