It is the parents' fantasy.
They are using their child as a social experiment with side benefits of earning income through publicity.
Follow up on this story in ten years time and you will see one fucked over teen.
Ah so you're all about anecdotal evidence to support your views! How about, there is a chance that this kid will, later in life, want to identify as a man. It doesn't matter, these are the years when children begin figuring out how to interact with other people, how to form friendships, relationships, work together with people, have fun with people. We all only have one shot at being a child. There are no do-overs.
Someone you are describing, you let this person slowly figure it out over time. What these parents are doing is making their child feel like an outcast in these crucial years.
This is the parents' social experiment and the chances of it working out to be the best for him, are slim at best.
