Well, fortunately this is an issue I have to deal with personally, but from observing other people's kids growing up, I can assure you that you don't need to worry about actively indoctrinating SteelyKid in the ways of gender identity. Society will take care of that quite handily.

I am honestly baffled by the pinkness of little girls which goes on these days. I live next door to an elementary school, and see the little kids going to school every morning, and the youngest girls are overwhelmingly dressed in pink. That isn't the case for the older (4th grade-ish) girls, and it's not like pink is female-exclusive for adults. So...?
