Also, I think I've figured out the perfect gender symbol for genderqueer people! Pluto's astrological symbol.
Meaning: "Mind (crescent) transcending matter (cross) to reach for divine spirit (circle)"
Maybe, but to the average person, it's a "female" symbol in which the circle is in a bowl for some reason. I'm rather fond of the question mark symbol, let me find it and I'll edit it in here.
