Your replies are trivial. And they undermine your case. As does silly tit for tat point scoring.
A fall is not gravity like a woman is not gametes - that is my point.
Just as one does not need to know the mechanisms of gravity to see its effect, one doesn't need to know the mechanisms of biological sex to see its effect. And my wording was "mechanisms of biological sex". Not "gametes". Mechanisms of biological sex.
Female humans exist. We are different physically to male humans. This is an observable fact. Female humans are in our language named "woman and girls".
For some reason, you want those words, and those words only, to name something else.
Fine.
But the reality of female people will continue to exist. And you have not made any case whatsoever for why the words that name us should be deployed elsewhere.
I have never made any objection to recognising and labelling whatever it is you think Gender is under its own name. Only to appropriating the existing language of sex. That is the case you need to make if you want to prove your beliefs are fair and reasonable. To stop looking only at trans identities and consider the bigger meaning, the human meaning.
And I have never ever seen an honest case for this made yet.
