Mm, that reminds me of a bit I read about the term 'sexual preference' being contentious and possibly a dogwhistle in homophobic circles, given 'preference' insinuates that sexual attraction is a choice which goes against current understanding of (example given) homosexual or other binary orientations, which, hypothetically again, goes against the sort of liberation sought by evaluating orientation via the Kinsey scale.
I'm not trying to offend anyone, but isn't the Kinsey scale still a simplification of representing orientation, as much as binary orientations are a (even more of a) simplification of representing orientation? Not that it's a bad thing; go too complex and people won't understand you, which defeats the whole damn point of describing your orientation to people.
I mean, consider this complex system: there are 4 variables, "romantic attraction to same gender", "sexual attraction to same gender", "romantic attraction to opposite gender", and "sexual attraction to opposite gender". Each variable can have a value from -1 to +1, -1 is "maximal repulsion", +1 is "maximal attraction", and 0 is "completely neutral", and each variable is able to take any value in between. For those familiar with vectors, yeah, this is describing orientation as a 4-dimensional vector. There are 4 independent variables at play here. Someone who is completely asexual and aromantic (and I mean completely, wants-absolutely-nothing-to-do-with-it, couldn't-care-less, but isn't repulsed at all) would be classified as a (0,0,0,0) under this system.
This is a very detailed way of describing orientation, though that's not to say that this is
the most detailed and accurate method possible; I'm sure those in the LGBT community can extend it with more variables, split variables further, or so on. I'm not sure if it works for nonbinary people, for instance. Its main problem is that it's too complex to reasonably be used on a day-to-day basis. Imagine trying to describe this system to people every time you want to describe your orientation.
I believe there's a tradeoff here. Too complex, and you end up confusing people. Too simple, and you end up excluding groups of people. It's good to avoid excluding people, but it's also bad to end up with a complex system that people can't understand. Where you stand on this is your own opinion, and I won't stop you if you want this complex system. Personally, I use this 4-variable system internally to keep track of myself, but when describing myself to others, I drop down to the binary orientation representation, because I have a personal belief that people's time is money, and that the less time people spend interpreting things, the better.
That's my opinion on that, anyway. I'm sorry if this offends you; I'm just trying to make a point that every system to describe orientation is just a simplification of the underlying truth, however close it might be to that truth.
