These are very informative. What fascinates me about intersex conditions are how different people who have the same type of it contextualise their situation differently. There's a "societal" element in it still. For example with the case of AIS, where the person looks female but is genetically male and has internal testes.
If you've seen a blog by ClaireCAIS, who see own's sex as female and seem to be very insistent of identifying as a woman and anything else would offend Claire.
Then there are people in these blogs who seem to accept the truth of "flesh, blood and gene" with any incongruity that comes with it. While they're legally and ostensibly female and feel fine with it, they have recognised that they're actually male - in a sense. Then there are a few cases who got the X gender markers as that became available. (A case in California I remembered, the person looked like a very normie in hiking gears and not like these danger hair enbies we're seeing)
This is nothing to say about troons though. Being born with characteristics that are not normally male/female and deluding yourself that you're supposed to be a different sex is a very different thing. While I'm not intersex myself, I found these things very frustrating because the conversation about difference in sexual characteristics were lumped into the "reasons" for trans identity which has nothing to do with it at base. I think there's a point to make that humans are still visual creature that doesn't judge the world by "unseen" things. Or else we'll see each other as nothing but some carbon atoms and other elements. And medical science still operates on that level somewhat.
For example, if you talk about race and skin colour. Actually "White" and "Asian" people have light skin due to a mutation in OCA2 gene. Which is incidentally the most common form of albinism in "Black" population. People with this mutation tend to not be as pale/light-haired/eyed compared to "classical albinism" (OCA1), which is the most common type overally. So even a similar mutations can get framed socially differently - one became something medically significant to have a light-skinned child popped out among dark skinned people, and one simply became incorporated into ethnic line at one point in the ancient time. This is though, different from intersex conditions - it's just something on top of my mind.
So I think there's a lot to think about the relationship between actual genes mutations, how things are framed medically, and how things are framed by laymen. Again.
