Actually, this seems a lot less disturbing to me than if, say, there were many different colors for boy clothes, but only pink clothing for girls. If you wouldn't feel obliged to avoid dressing a baby boy in blue, why feel obliged to avoid dressing a baby girl in pink? None of this has the moral that gender differences in general should be downplayed; it's when you start saying that male-is-default or 'people can be nerds but girls have to be girls' that you have a problem. In general, I think the mode of thought to be fought is that males are colorless and women have color; or to put it another way, the deadly thought is that there are all sorts of different people in the world like doctors, soldiers, mathematicians, and women. I do sometimes refer in my writing to a subgroup of people called "females"; but I refer to another subgroup, "males", about equally often. (Actually, I usually call them "women" and "males" but that's because if you say "men", males assume you're talking about people.)
