This slightly makes my brain hurt. Yes it might be a good thing to widen the perspective on gender roles, or on any role for that matter.
However, if this is not done on a larger scale, ie entire city or country, this will in all likelihood be very confusing for these children when they reach school age, and interact with children with a different upbringing.
I am not saying that this is right, in fact it is very sad, but it is equally sadly the truth that anyone who behaves differently, in school, will probably be bullied silly. Not that this means that we cannot change things, or should not, but it does mean that radical things like this, needs to be done on a much larger scale or else its effects will be ruined within a few years.
Also, more specific to the program itself, it has some good ideas, but as usual, takes it too far. What is wrong with saying "him or her", why invent a word that has no practical use? Why only homosexual and single parent books, isn't heterosexuality an equally valid sexuality?
I would also love to see the gender diversity among those who work there. Not to be prejudiced but I seriously doubt that it is a fifty-fifty divide between men and women there.
