I wouldn't say that "there are only two sexes" is nonsense. That there are two poles, masculine and feminine, with varying shades of sexuality and physicality in between, seems a fair way to put it. This is the perspective I hold.
If people want to move outside that, fair enough, don't think it's realistic to assume that everyone can or should educate themselves on every way of life that people might choose.
Trinsec, I see where you're coming from, although I think many people hold reasonable common sense notions regarding sexuality. I don't think it's fair to categorise people who tend towards natural gender roles as uneducated (not including bigots who want to hate on anything they don't understand.)
