http://dramarising.tumblr.com/post/89425062553/the-term-intersex-is-an-incredibly-simplisticI'll quote the two things that stand out most to me:
I’m just going to highlight the fact that any stigma against intersex individuals is particularly stupid. We are all intersex and produce testosterone and oestrogen though the amount varies depending, again, on (guess what) epigenetic, genetic and environmental factors. Oestrogen even comes from testosterone and is made via chemical modfication x’D
I . . . don't think that's how being intersex works? We have those hormones because they have other important functions besides denoting sex.
The fact that transgendered and intersex individuals even exist suggest that there’s a possible benefit in having variation in sexual identities. If all the XX and XY individuals became disadvantaged due to an environmental change, then perhaps XO and XXY would be fitter and the human race wouldn’t just die out. The same with gender identities.
I don't think that's how evolution works, either (i.e. if it exists, it must be beneficial somehow). Seriously, they make it sound like there's some sort of "plan" in motion, and that intersex people are meant to be some sort of failsafe for some unspecified hypothetical disaster that will only affect XX and XY individuals, leaving the intersexed and trans* people to be the saviors of humanity. It actually kind of reminds me how the director of
Melancholia believed that depression made people "smarter" and "more aware", and that if these very specific circumstances happened, they'd totally be the only sane people! As Oancitizen put it, he has to bring literally the entire planet into a state lower than himself in order to "prove" how depressed people would be better than "normal people".
And no, I'm not comparing intersex and trans* to something harmful like depression. It's just that the OP's straw grasping about how intersex could be an advantage reminded me of
Melancholia's straw grasping about how depressed people would be "saner" than "normal" people; by having everyone not like them in a situation where they'd suffer more.
