Well,raising someone gender neutral shouldn't be a problem I think? Idea being not that you'll end up with children with no idea of what gender is, but that your kid would be more at ease without having to conform to society's perception of gender.
Peoples crave an identity, if you remove gender it will be something else. I believe that gender neutral isn't the right way to go, and that being more permissive with gender definition will be much more beneficial.
But you have a lot of leeway on how you define gender-roles, roles in society and values in general.
Look what "being a man" was before. Read Duma for instance. Aristocrats wore heels, pretty jewels-adorned coats, make-up, and held culture and refinement in high esteem. They spoke of how their pants hi-lighted the gable of their legs, and made sure they had delicates hands.
They were also ruthless killers that would stab you for looking at them the wrong way.
That's just it. People do need identity, I agree. But let's rephrase your sentence:
"If you remove gender, people will make
their own identities." Their own, as opposed to whatever gender roles are shoved onto them.
As an example of this: At camp, while I was away canoeing with a small group, we went to a beach. We had the option of going swimming or hanging out and making bracelets. Without thinking much of it, I went to the shoreline - but then noticed something. All of of the boys were swimming. Almost all of the girls were making bracelets. This alerted me to a subconscious choice based on a gender division. But did
I want to go swimming? When I thought about it, no. The river was slimy, and I like making things with my hands. So I went and made bracelets and talked with the girls and had a much better time than I would have if I had swam.
Nobody stopped me from going to swim. I had that option at every point, but I didn't go swim. Gender neutral parenting doesn't mean forcing your boy to do girlish things. It means letting your boy do... anything, whether boyish or girlish, and trying to help your boy see that it's okay to play with dolls - if they
want to. If they like trucks, nobody's stopping them from playing with trucks.
It's a common misconception that gender neutrality, feminism, etc., takes away choice, when in reality it takes away nothing. It only gives a choice.
