I'm not sure how I feel about this. At first glance, this seems really ridiculous, but it's actually a pretty complex matter, starting with what gender identity is and when and how it's formed. I feel like I'm currently not informed enough to have a strong opinion about this.
That's child abuse. I don't think any parent should push their kid to be trans or put any kid on hormones before they're 18. Kids are too young make that kind of choice. If the kid wants to become trans, they can when they're grown. Also, hormone treatments destroy a person ability to have kids.
As far as I know, it's not a choice usually. It's about identity that just comes to be as a person matures.
