Non-binary genders are something I've always had issues with. As in, I have trouble with gender, because of societal portrayals and common ideas of how a girl/guy should act. A lot of people just sort of cast away identifying as either. Doesn't really change anything about their sex or sexual preferences, it just sort of makes them feel more comfortable. Most people are gonna feel comfortable with identities, but I think it's important to let those who have issues with it do what they want.
Ain't harmin' no one.
