Actually pretty interesting. I think we're starting to creep up on the actual numbers, as far as you can measure such a thing. I think comphet keeps a lot of people who would otherwise fall somewhere on the bi/pan spectrum from ever experimenting and realizing it about themelves, and I bet that population is actually quite large. As far as transness goes, I would be willing to believe a number within the realm of ~3% to even 5%. I think further complicating this whole thing is that human sexuality and gender identity is a lot more nebulous than the very rigid, medically-originated terminology we use implies. A lot of the identity labels we use (homosexual, transsexual/transgender, etc) were originally medical diagnoses that were later transposed onto cultural identities, which carries a lot of baggage that I think has been left unaddressed, such as the rigidity of their definition, but that's probably for a post for another time. Anyway, just thought it was neat neat, especially the state queerness leaderboards.
Now that I read the rest of your comments in this thread, I think you probably should make an effort at Homosexuality.
And to further derail this thread from days ago, since I see you are appreciating Jules Gill-Peterson, I am very curious about this conversation I heard with her. I was thinking of making a post about it, maybe it doesn't fit in here. I am not intending to make you feel like cornered or pressured.
In this interview conducted by Morgan M Page starting around 55mins she is talking about her new book, which is a criticism of "transgender politics". She says that transgender is a concept created by elites (particularly trans* elites) which uses identity politics to repress and control trans* people. The whole concept of transgender is regressive and harmful. That it explains things such as the hostility between trans people and medicine. It's a short, informal discussion so the ideas are not well developed here, presumably in the book they will be.
I don't know what her underlying political orientation is so I am cautious of making inferences regarding the gaps one way or the other. I don't know if this idea is generally circulating anywhere or if she's really just gone off in her own direction. I have heard an approximation of this argument before but never strongly made, often sounding more like pettiness or a kind of inverted respectability politics.
