The reality is apparently that she's bisexual, which we supposedly know immediately, and who spends all her time flirting with girls, but somehow she starts fainting at the sight of them. So she goes to your male character for help, who then drugs her so she sees him as a girl so she can get more comfortable with the gender she apparently flirts with constantly. Afterwards, she's better and loves your character. Also, the supposed bisexual can't be romanced by the female Avatar, because that's just too much gay. And this is the version we're supposed to believe based off of an unsourced imgur post.
So, what I gather from this is that, if we are to believe the latter is true (I say believe because, you know, saying how wrong other people are doesn't exactly mean you yourself have proof), people were getting upset for the wrong reason. They should have been upset for basically making a bisexual character whose bisexuality is reduced to shallow flirting with other girls before she runs back to the boys for real romance.
