Yknow what always makes me laugh about certain anti trans folks is that they think “biological sex is immutable” is something that trans people disagree with. Like, yes I’m well aware that I remain biologically male despite transitioning I’m not an idiot. Your sex is immutable - the concept of sex isnt as clear cut as is often implied by this statement, but nothing is going to change your chromosomes or whatever.
So that’s actually not true, but for reasons that I think are weirder and more interesting than anything implied by either side of this “debate.”
There are actually about 50% more women who have Y chromosomes than originally expected, and also: microchimerism seems to be extremely common in people who give birth, seemingly regardless of whether or not they give birth to children with XY chromosomes. But the genetic remnants of fetuses that have XY chromosomes stay in the body for many years (possibly a lifetime), and this has a fairly significant effect on genetic composition.
I get what you’re saying and I don’t totally disagree, but I think the main thing that I keep learning is that “biological sex” is just not actually a particularly meaningful concept.
Biology actually has a lot of difficulty nailing down words like “species” as there are many useful ways to define a species in biology. Its not surprising that sexuality is a also a concept thats hard to pin down in biology. It is similarly highly useful in biology to define sexuality in multiple different ways - genetically, morphologically etc, but as a concept it doesn’t always fit perfectly and its an area where evolution likes to experiment, even in humans.

Would you care to elaborate on this, and preferrably add sources for your statements (or pm me) so I can read further?
It’s “meaningfulness” is secondary - it is most certainly a highly useful concept in the science and practice of biology and medicine.
