Yeah, the actual numerical differences are definitely where the problems start, but I sort of intentionally sidestepped that because it only explains why there aren't more femslash ships period, not why I'm less interested in f/f ships and femslash when I do encounter them.

It's an interesting point about Suki. Contrasting her against characters like Ty Lee or Mai, I do feel like I have less of a sense of her character besides "is totally badass" and "likes Sokka." Funny how that happens!
