I know I'm late to the party when it comes to commenting on the whole "child raised without a gender" kerfuffle, but I wanted to say this:
I can't think of many things crueler than going up to a child and saying:
"Hi, little Storm! Welcome to the world! It's a big exciting place! But there are a few rules. Some of the fun things you see, you won't be allowed to do, even though other kids do them, because of the way you were born. You're able to do these things, and maybe you'll want to, but you're not allowed, because everyone says so. And if you do those things you're not allowed to do, other kids will make fun of you and grown-ups will think there's something wrong with you and when you get a little older you might even get beat up! In fact, you're not even allowed to want to do these things!
Because of how you were born, little Storm, there are clothes you can't wear, clubs you can't join, ways you can't talk, toys you can't play with, sports you can't play, names you can't use, haircuts you can't get, and entire ways of being and acting and expressing yourself will be closed off to you! For no particular reason!
Have fun out there, and remember, don't do the things half the other kids are having fun doing, or you'll get in big trouble!"
Now that's permanently damaging.
