The Film 'Inside Out'

People have talked about the Numskulls in DC comics (was it The Topper?), and idly I'd thought about all those people running around and peering out of the inside of the Statue of Liberty's head.
But doesn't anybody think that it's remotely weird that the Pixar film Inside Out, about the goings-on in a little girl's brain, is written by middle aged men? I know one of them is the father of a little girl, but he's never been a little girl, nor has he been a teenage girl.
It is peculiar in the extreme that it's seen as normal that men should articulate what girls feel, to an audience that includes girls who may well not be aware that what's happening on screen is manipulated by daddies.
UGH!!!
