I'm not sure if this has been discussed here or not, but in Toronto, ON there is a couple raising their newest child to be genderless. They have not told anyone what the gender of the child is, and plan to keep it that way. Their two older sons (aged 2 and 5) get to choose what they wear, how they wear their hair, what toys they play with, whether or not they wish to paint their nails, etc etc, without consideration of gender. They also do not attend traditional school, and rather are being "unschooled".
Link to the article. It's long, but interesting. What do you think about this?
