What's REALLY behind today's youth transgender craze?

I've read a number of theories but if you look at the statistics, it is largely white kids and they've been told that what they are isn't acceptable. However, transgender is celebrated and so that's what they say they are.

It couldn't be that Hollywood is constantly bombarding them with shows and movies where they are portrayed as always happy, always a functional human being when every straight character is falling apart. Nah, that couldn't be it.
