At the risk of getting slightly political, this can best be seen in the massively exploding rates of LGBT self-reporting, which has seen a 5-10x greater representation amongst the youth in a lot of studies. This isn't explained by "society being more accepting" or "people discovering themselves" because this has happened very quickly in a very short time. The best hope is that this is just a fad like people's "scene/goth phase". However the worrying part is that instead of people looking back at their highschool photos and thinking, "man, I can't believe I dyed my hair that color and had it cover my eyes", the new youth will look back and think, "man, I can't believe I chopped my penis off."
