Find me a girls' magazine that isn't about sparkling up your fingernails, braiding your hair, one direction (band) or some other useless shit. Then look in the boys' section and you'll see what I mean.
Same goes for adult women except they can skip straight to grannies' knitting magazines if they choose to.
I have a daughter that I'm trying to shield from this and it's really hard. I don't even know what to say when she asks why there are only pictures of boys in her favourite arduino magazine. Same for lego technics. Unless you buy lego with princesses or animals, pictures on the box will be of only boys having fun. The game is rigged.
