Child abuse, pure and simple. When I was 7 years old, I wanted to put on a cape and jump off the roof of my house.
I think you make an excellent point. This is the latest fad -- letting children live their lives as they wish at the age of 5 or 6. It reminds me of the fad in the eighties of believing 3 year olds who insisted they'd been flown to Miami, during the hours of daycare, and raped during a porn-filming. And then flown home again by 4pm.
Everyone believed them. Now, the little boy in question may well grow up to have "gender" issues. But his parents are absolute dopes to cater to it this much at this age.
He's sunk.
We did jump off of the house!
