God is absolute and so is gender assignment...
Science fact: You cannot change the sex of an individual at the biological level. EVER...
Yet people today, even police organizations, insist on being biased in favor of what is not scientifically possible, all for the sake of being politically correct and emotionally sensitive to the snowflakes out there who insist that they can reverse what God created.
To be clear science at it's core does not support the twisted definitions placed upon gender assignments as done by the society at this moment or any moment. It seems that opinion, once again, is trying to silence science as it does in the case of the murdering of the unborn.
This is a good read that digs into the real science of the matter rather than emotional opinions:
Sex Change: Physically Impossible, Psychosocially Unhelpful, and Philosophically Misguided
"Sex is a provable characteristic. Gender identity is not. To acknowledge sex as a immutable characteristic is not a belief but a fact. What's wrong with UK cops? Won't arrest grooming gangs because racism, won't hire people who know what biology is, but rainbows everywhere!"
"Modern science shows that our sexual organization begins with our DNA and development in the womb, and that sex differences manifest themselves in many bodily systems and organs, all the way down to the molecular level. In other words, our physical organization for one of two functions in reproduction shapes us organically, from the beginning of life, at every level of our being.
Cosmetic surgery and cross-sex hormones can’t change us into the opposite sex. They can affect appearances. They can stunt or damage some outward expressions of our reproductive organization. But they can’t transform it. They can’t turn us from one sex into the other.
“Scientifically speaking, transgender men are not biological men and transgender women are not biological women. The claims to the contrary are not supported by a scintilla of scientific evidence,” explains Dr. Mayer."
Or, as Princeton philosopher Robert P. George put it, “Changing sexes is a metaphysical impossibility because it is a biological impossibility.”
To wrap this up as the final and ultimate authority on the matter here is God's position:
For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse:
Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened.
Professing themselves to be wise, they became fools,
And changed the glory of the uncorruptible God into an image made like to corruptible man, and to birds, and fourfooted beasts, and creeping things.
Wherefore God also gave them up to uncleanness through the lusts of their own hearts, to dishonour their own bodies between themselves:
Who changed the truth of God into a lie, and worshipped and served the creature more than the Creator, who is blessed for ever. Amen.
For this cause God gave them up unto vile affections: for even their women did change the natural use into that which is against nature:
And likewise also the men, leaving the natural use of the woman, burned in their lust one toward another; men with men working that which is unseemly, and receiving in themselves that recompence of their error which was meet.
And even as they did not like to retain God in their knowledge, God gave them over to a reprobate mind, to do those things which are not convenient;
Being filled with all unrighteousness, fornication, wickedness, covetousness, maliciousness; full of envy, murder, debate, deceit, malignity; whisperers,
Backbiters, haters of God, despiteful, proud, boasters, inventors of evil things, disobedient to parents,
Without understanding, covenantbreakers, without natural affection, implacable, unmerciful:
Who knowing the judgment of God, that they which commit such things are worthy of death, not only do the same, but have pleasure in them that do them. Romans 1:20-32
With all this said, God is absolute and so is His creation of gender assignment...
