My cats are sleeping in the exact same position. I'll get a pic up soon.
Why am I never called upon for my voice of stupid?
I think this is the way to do it. In the US, genders are given based on your gentials, and that's it. Boy, girl. I agree that the unassigned gender system is brilliant, just let the kid do what they feel like doing, and let the kid decide who they want to be.
