Unless a pollster makes some effort to filter gays out of the responses their opinion can be amplified up to 11Times their actual representation in the population.
Remember too that homosexuals have long been working their way into political, media and other areas where information is distributed/legislated. There are a number of ways they amplify their numbers/influence and strangely enough they all crossrefrence. A perfect circle of propaganda.
It’s the global warming consensus model.
I know that the Kinsey Report was 10%, done mainly with inmates who probably fit that percentage, and that 10% crap was then spouted as if it represented society . . . and the media have, in many cases, glommed on to it.
