I don't believe there actually IS an "intersex community'. There are intersex organisations but they don't appear to exist to serve most of the various disparate and unrelated syndromes. Perhaps because so many of the syndromes are not remotely "inter" the sexes at all.
Many, perhaps most people with the various disorders or syndromes that are swept up under the so-called intersex umbrella are unaware of the other syndromes - and why would they be?
A woman with Turner's syndrome has no more in common with a man with PAIS, than a woman without the syndrome has with any other man.
Why would they? We don't expect special commonality between women with thyroid conditions and men with broken ankles.
You could contrive to label them both medical conditions under a similar banner if you were inventive enough, but there's no earthly reason why they should be lumped together really.
When I spoke to a relative about her Turner's syndrome and how she felt about it being used as an 'intersex' condition gotcha for trans rights, she seemed unaware that Turner's even WAS an 'intersex' condition. Noone had ever told her it was called an intersex condition. To her, it was just one of the health conditions she dealt with and went to clinics for. I go to my diabetes clinic, I see my joint replacement surgeon, I see a doctor about my Turner's.
Because Turner's is in no way inter the sexes.
It's entirely, unequivocally, a 100% female condition. She attends a Turner's support group once in a blue moon. She's never met or been invited to meet groups of men with Kleinfelters or 5ARD. Why would she? There would be no earthly point. And noone has thought to create such a group because it wouldn't serve the needs of either party.
Unless it was to serve an entirely unrelated agenda.
It wouldn't surprise me if most people with DSD syndromes are both unaware of most of the other syndromes bundled under 'intersex', or even that their own syndrome is under that banner.
