I'm against this kind of parenting. I don't see how this is helping children being raised this way. Unless the child says he/she isn't why create void that will could confuse the child. Not to mention affect his/her socializing with other children.

Now I am in favor of gender neutral toys and colors. Remove the stigma of pink for boys and crap like that. Let a boy plays with dolls if he wants or a girl with trucks..etc

If you have a baby boy, raise him as a boy until he says he is a girl. If he wants to play dressup let him. He can do that and still be a boy (and vice versa). If you have a girl, raise her as a girl, until she says she's a boy. If she wants to play tackle football, let her.

If the child is intersex, don't assign a gender, especially NO surgery until he/she tells you what they are.

You can love your child without messing with their socialization with other children and by extension other parents (who might not want their kids to play with the weird kid).
