I heard this recently and didn't make a note of it. There is a modern thing, could be an element of diet, or medical thing (like vaxes), or was it fluoride in water? I cant remember but there was research that doing this thing was found to make animals in tests become GAY, but not until TWO generations had passed. (and we started doing it two generations ago).
If anyone knows this please let me know, I wanted to follow up and try to find the sauce and research from scratch... thanks.
EDIT: Yes I think it was "The Pill". You see - I have a theory, unlikely to ever be tested, that these individuals, the men anyway certainly, have also a physical marker that this has happened to them. I call it "Gay mouth". It's a strange kind of underbitey kind of thing, subtle, but it uncannily predictive when you begin to be able to spot it. Brian Stelter has it (the fat CNN host) for example. I've seen many many examples.
You might even wonder whether "gay lauding" (privileges) of the modern type is an effort to reduce the damages the pharmas would be liable for if this ever goes mainstream.
Not certain about your specific question, but a related thing I read a few years ago said that millions of women on birth control pills (containing estrogen) do not absorb all the estrogen and the excess ends up being urinated into the sewer systems and back into the water supply. Most water purification methods cannot remove estrogen, so it ends up, back in our drinking water.
I suspect that higher levels of estrogen in drinking water might contribute to the increased homosexual and transsexual desires of both boys and girls... it messes with their natural hormonal development. In the absence of a strong moral society, young folks feel free to give in to those unnatural urges and we get the kind of "society" we see today as a result.
