Marvel is selling these two shirts, the left one for boys and the right one for girls.
What kind of subtle sexist messages are we selling to children with these shirts? Some people have said that this is no big deal because the shirts are marketed to kids, but I think this actually makes it worse. Childhood and adolescence are when most people form a lot of their ideas about the world including how they relate to the other gender. Of course some people overcome those ideas in adulthood, but many will not. It is a bad idea to start kids out by providing them with sexist gender stereotypes before they are even old enough to fully understand what a gender stereotype is.
We already have enough of this stuff from religion. I expect better from my nerdy icons.
