That’s such a funny post PN.
It supports your bias, whilst denying anyone else’s.
Of course nature changes, but changing it by cutting off bits, adding bits or simply identifying as something you are not, and using that identification in a way which harms others is not nature evolving.
People’s willingness or unwillingness to accept lies is also evolving.
There are only two biological sexes, and sex is immutable.
I am not and will never be a 2m leggy blonde, but saying I am, harms no one except me, because I can never be what I want to be.
On the other hand, cloning someone’s identity, claiming to be them, dressing like them and demanding to be accepted as them is harmful.
