They're not saying she's gay, they're saying
Disney is showing girls don't need guys and pink and butterflies and makeup
to be happy, which can possibly strike the same cord as lesbians.
I watched the movie and in any moment I tought she was gay.
But there was a character that I did tought was gay, the son of one of the lords, when he says he is not interested in girls, or something like that. I know he didn't say it in that way, but it could also be double sensed...
