Well... I read a study one time, it was an "historical survey' so the numbers should be taken with a LARGE grain of salt, but they did a decent job with the stats and it turned out like 6% +/- 2 of "true biological incidence" (as distinct from cross-dressers and such). I don't remember where I saw the study, I can try to find it if you wish.So are you saying people who truly have gender dysphoria and are biologically gay are in and about 6%? Cuz I’ve been trying to find numbers on the percentage of people with a true mental illness and not just “acquired taste”.
I'm not sure I'd put too much stock in the specifics, to me it registers as "ballpark 10%, maybe a little less", which dovetails with what I know about other species.
That's kind of what I was saying about the 20% figure, the only way you get that is through the politics, like for instance if you're lumping all of LGBTQ+ into the same bucket. Biologically it's not the same bucket. Cross dressers are not necessarily the same as homosexuals, they "might" be but they also might not be.
