I brought this article up with my spouse, and we commiserated at Disney/Marvel's lack of desire for a wider audience. (At least, in their toys. Marvel's stories, especially in the comics, has become incredibly diverse as of late, while their movies are moving in that direction.) Cups overheard us, and she became angry as well. My spouse suggested she write a letter to Disney about it, so off she goes to get paper and a pen to write her letter.
We have a 4-year-old as well. Cap'n was also around, and not to be out done by his big sister, he wanted to write a letter, too. He said he likes girl superheroes and wants more toys with them as well. I had to help him with the writing of the letter, but he told me what he wanted to say and signed it himself.
Their letters finished, Cups went off to search for envelopes and stamps, since she was fully intent on mailing the letter. (And we'll get to that, as soon as I find the right snail mail address for it to go to.)
Cap'n went off to play with the Rapunzel play dough set.
