So first and foremost, I am not defending these idiots at all, just looking at what they have actually written. I don’t believe that they are behaving sanely, let alone reasonably.
It’s not circular, but is in a practical sense retrograde, since it involves making a determination at birth based on criteria that cannot be accurately assessed until some point in the future. Therefore, obviously, the way the sex is actually determined at birth isn’t going to align 100% with the definitions they’ve outlined here and is going to cause some massive problems for subset of humans who don’t deserve any of this. As a result, they’re not sidestepping issues with chromosomal variability so much as walking head first into them, like a steel post.
I completely disagree that this definition is “not tethered to any objective fact”, because whether or not you produce sperm/ovum at some point over your lifespan definitely reflects an underlying reality and is how sex is determined the rest of the time when we aren’t talking about humans and social issues.
Yep, the courts and lawyers are definitely going have their hands full.
