This all seems completely nuts, doesn't it ! I believe I have it figured out though.. here's my guess.
Like it or not, there seems to be an oligarchy of super billionaires, who are pulling the strings on nearly all of the highest politicians. ..And they are doing their dirty work on an international scale.
Nearly all these super rich people are concerned with 'population control', and they are afraid that if people in the world keep reproducing, it would force each one of their kingdoms to shrink, therefore they would like to see some kind of birth control..
We know there have been charges by some, that certain billionaires have tried to sneak sterility devices into unwary populations.. Don't know if those charges are true..but they have been made.
Now, suppose the oligarchy wants to cut population. Would they use all their devices, entertainment, TV, pop culture and educational systems to push for LGBTQ and other devices to put a positive light on such activities, knowing that every weirdly concocted relationship..so long as it is not male+female, will not reproduce.
If that were so, it would cut the rate of population growth, over the next few years.
