I once read a few books of the “Battlefield Earth” decacology. One of the interesting predictions in the book was the active promotion of homosexuality as a population control measure, a cure for overpopulation.
There was a Hawaii Five-0 episode a while back where they crack the case of a deranged (female) scientist intent on spreading a deadly virus to college-age students at an international youth gathering.
Her sick justification, when she was busted, read almost exactly like the population control lobby among the libtards.
Until capitalism came along and brought with it freedom, innovation and productivity, the earth maintained a fairly stable population of half a billion people for millenniums, give or take a few million. Your most extreme libtards believe that is all the earth can sustain, though a few concede that technological advances will allow us to sustain perhaps as many as five times that number.
They, of course, are the proper ones to decide which one-third or so of humanity gets to survive. Really scary stuff once you understand the mindset.
