Any attempt at making DSD occurrence equivalent to “demonstration that transpeople exist in nature” is beyond stupid on the very logic employed by the trans proponents of “sex is not determined biologically “.
In fact the existence of DSD indicates that sex or genetics actually does make you something (of a certain sex) not, as they would have it, that genetics/biology has no role in determining sex.
its the fact that anomalies can occur that demonstrates that sex is determined biologically.
Any insistence that the existence of chromosomal variance disproves that genetics (biology) has no role to play in determining sex or “gender” is so flawed by their own reasoning it’s laughable.
assertions that the way to understand being trans is not via “false” reliance on biology but yet relying on biological anomaly as indicating “something” that supports the contention that being trans is inherently natural (just not biological) removes the justification for claims to having a requirement for “lived experience” to understand being trans.
Obviously it is in fact one of the other - if biology were to be primary (as we know it is) then on their logic genetic variability on sex chromosomes would mean everyone with a genetic sex chromosome anomaly would be trans and they are not.
The trans argument nodding to DSD (but people are not always born xy/xx!) is based on something they think is clever - switching nomenclature into primary position over physical determination (an equivalent in philosophy is the argument of “solipsism “). Usually we think x exists and we call it y but when we add p, t and Q we add x with p “description”. They are saying x doesn’t exist (biological woman) BECAUSE p, t and q has been observed. But p, t and Q don’t exist separately to x - they are characteristics that sometimes occur and in nature. None of p, t and Q are observable other than occurring in nature and they don’t pre-exist X or cause into being some further entity “B” - which has only every been described but not observed in nature.
And, of course, if someone has no language or understanding of language then their argument fails on another hurdle because evidently something- something physical- pre-exists naming or there wouldn’t be something to name.
One cannot call a tree a tree were there to be no physical entity to refer to. Suggesting that “female” or “male” is not linked to biological reality acts as if naming were utterly devoid of a relationship to anything other than words attaching to words - as opposed to sexed actual objects being ascribed names by consensus.
There is nothing remotely logical about the arguments they use against biology (or language for that matter).
