I think kids will play with whatever they want to and if they have a good imagination what you see, eg an airoplane, might actually be a gun. And the gun might be a spaceship.
And that doll is actually a robot, or even a soldier.
Even without toys, kids with good imaginations will use sticks, stones and furniture as whatever toy they want at the moment.
Anybody getting upset about a toy not being gender appropriate is the one with a problem
