A puzzling thought about LGBT

An idea has been percolating inside my slightly warped brain. Well, maybe I'm a quite a bit warped. You decide.

When I was a kid sixty years ago there was little evidence of LGBT. I only knew of Christine Jorgenson and in the sisties a movie 'I want what I want'.

Anyway, here is my weird hypothesis:

With the rapidly burgeoning world population and the seeming lack of will to control it, perhaps the swelling LGBT ranks is simply a bit of natural selection to curb population growth. LGBT couples could adopt the unwanted/excess births to fulfill family desires.

Comments?
