Mckenna makes a change that in some ways seems so small and yet when you really think about it, opens the gender bias door for a lot of people. You see it happening more and more. Another perfect example is Goldiblox, inspiring young girls that engineering is cool for girls too.
I think this sort of thing is great because when you are a kid, your imagination is at it's peak and your desire to learn is in over drive. Why not give every little boy and girl the chance to try every toy to help them find their true passion. The world can always use more great cooks!
