A few important points.
Halfway through gestation, male mammal fetuses excrete a bit of testosterone from their testes, which goes to their brain and tells it, it is a male brain. If that testosterone does not arrive, the human brain is female by default.
In animals this is enough to determine their mating behavior, BUT NOT IN HUMANS. It DOES NOT determine either sexuality or sexual attraction in humans.
But what it does do is strongly influence a child as to whether they have masculine or feminine behavior. A very masculine woman can be very heterosexual, and a very feminine male can also be very heterosexual. IT DOES NOT MAKE ANYONE GAY.
However, it can result in truly impressive gender identity confusion. This can be very pronounced to the point that a child deeply dislikes their natural gender, and in rare cases, it can haunt a child all the way to adulthood.
The dangerous part of this is that there are natural and artificial chemicals that can make this gender confusion much worse.
So the question becomes: is transgenderism legitimate?
If a boy thinks he is a girl, all the way through to adulthood, and suffers accordingly because he is not a girl, is hormone therapy and surgery acceptable?
This problem is not correctable through drugs or psychotherapy, it should be noted.
Psychiatry has no “easy” answer to homosexuality or even transgendered folks.
However, these things are not “all or nothing”.
And there is a good argument that the present day “epidemic” of transgenderism is due to obsessive/compulsive ideas being reinforced.
In Asian religions, (e.g.Confucius) one rejects one’s personal desires and does the right thing. Marriage doesn’t require love, but obedience to the role model.
So you quietly do such things in private while playing the role given to you in society.
For gays, it means in the closet, or else living on the fringes of society where there is a “space” for gays (e.g. theatre, transvestites in India, gay subculture in the Philippines).
In the west, you change society to “accept” deviant behavior.
The question is: Is this “good” for society? Will other children become confused about what is male and female?
A lot of the “culture wars” today are not about religion per se, but about the confusion of sexuality, where sexual activity is outside the sphere or morality, and male and females are the same in everything, ignoring the reality of sexuality in the personality.
Great for women with careers, who now are “free” to live as men, but not great for those who want to be moms.
