What???
So only women should 'worry about the girls' and not "worry about boys"? So the fathers don't or should I say "shouldn't" worry about their children either?
In your scenario of "well let the boys go out and get dirty, fight etc," what would you say if the boy doesn't want to do that but would rather stay home and do "traditionally 'girl' things" like play house or whatever else? What about if the girl wants to go out and rough house and go play in the lake. wander in the woods? My older niece did with very little interference from her father and (step)mother when she was young. She grew up just fine thank you very much. Isn't that 'labeling' or categorizing specific behaviors to specific genders rather than saying let all children play the same way?
Quite frankly what IS the difference between "building sets" and "girl building sets" anyway? They both have the same purpose... build something and play with it- so see no reason why both boys and girls can play with any of them.
I don't see it 'spreading'-- seems to me that some clothing is already unisex anyway and has been for many years while others will always be more preferable to female or male (including specific sizing)...
