As a rule, I don't engage with niche internet queer discourse on this blog. However, this specific behavior is one I have observed often enough that I suspect it might not, in fact, be limited to the online sphere- so in the interest of education let me speak about it once and then never again:
Saying shit like "I wish I were intersex" is intersexist. Full stop.
"I wish I were intersex" what do you mean by that? Do you wish you were androgynous? Do you wish you had both sets of genitals? Do you wish you were recognized as outside the binary legally? Because none of these things have anything to do with being intersex (in fact, in order: many intersex variations don't make you androgynous, no intersex variation can give you a working set of both genitalia, and plenty of intersex people in the world are still assigned a gender at birth. That's what the "coercively" part of "coercively assigned gender at birth" means.) Saying "I wish I were intersex" tells me exactly one thing, and it's that you have a fantasized vision of what intersex people are and no regard for what it actually is to be intersex.
Sometimes, I see people being a bit more specific- "I wish I had CAH, easiest transition of my life" "I wish I had hirsutism, so I could have facial hair." That's not better. That's still reducing intersex people to bodies with no regards for the hardships intersex people face in their everyday life. Let me put it this way: if someone said "I wish I were black so I could be perceived as more masculine," you'd understand that it's a very innappropriate thing to say, right? That reducing a marginalized community to "hehe gender goals" while completely ignoring the culture that comes with being part of that community + the (often violent) oppression they face is extremely dehumanizing? Ideolizing a minority is also a form of dehumanization. "I wish I had [intersex variation]" you wish you were subject to infant genital mutilation? To blatant medical malpractice? To medical rape? (Yes, that's a thing.)
There's also the fact that many intersex variations come with health issues. "I wish I had [intersex variation]" you want a body that can't pee? You want osteoporosis and chronic fatigue from hormone imbalance? You want infertility?
"Uuhhh no when I said I wished I could be intersex I meant I wanted the cool bits I liked not all the baggage that comes with it" and you didn't think for five seconds about how it feels to actually be intersex, endure all this shit on a daily basis, and then turn around to see people use your name while blatantly erasing your struggles?
Also, for the record: being intersex does not make it easier to transition. At all. Plenty of trans intersex people have spoken up about how hard it was to transition. Personally I'm fine with my body but I know that if I wanted to change it in any way I would need to jump through so many fucking hurdles. I've had people straight-up tell me "are you sure you didn't just think you were non-binary because you're intersex? you could just be a confused cis person who doesn't know being gnc is an option! :]" Being intersex does not make transition any easier medically OR socially, and you are a fool who didn't do the bare minimum research if you think otherwise.
