No. I'm not saying that hormones are not pertinent to sex categorisation.But previously you claimed that hormone profiles were fixed at conception (which is wrong even on your terms, they can change in utero). Are you now saying hormones are not pertinent to sex categorisation?
So how humans categorise sex has changed. It is fluid and therefore debatable.
But the fact it happens sometimes means it is also debatable whether chromosomes are always the best way to categorise sex. But you claim there is no debate, that your opinion is correct and no other opinion has worth. That's staggeringly arrogant, especially seen as you keep getting things wrong and don't seem to actually know much about this.
No. Gender is now fluid. Not sex. Sex is fixed. The debate is whether sex is the sole or should be the sole basis for gender identification.
Chromosomes are our sex markers. XX is female; XY is male. This is not a matter of opinion. This is a matter of fact. It is establshed. I did not establish it. Science did. That's why I say, you can't debate that.
