Good point in that birth genitalia and the mental start of sexuality at puberty are 13 years apart, so do not have to be in synch.

R5 is RIGHT again S2 #1,082."Three State Troopers over a restroom?" R5 #1,083
What will they do if that girl refused to drop her pants so they can check?Three State Troopers over a restroom?
What are you talking about?While that sounds better than toxins, these hormones are getting into the food chain, and greatly altering birth gender and puberty gender.
What are you talking about?
Gender identity is innate - "those people" were born that way. Gender non-conformity is not something that suddenly crops up at puberty. Fact is, children self-identify by gender at a very young age - as early as two or three, long before puberty is even on the distant horizon.

Just in case you are gullible enough to think bans on trans healthcare for kids have anything to do with protecting anyone’s health…

Gender identity (the sense of being male, female, whatever) is not related to sexual attraction. Children self-identify by gender at a very young age (as early as two or three) long before any sort of sexual attraction enters the picture.Neither gender has any sexual attraction until after puberty.
That is what puberty is for.
And without sexual attraction, there can be no gender identity.
You seem to be confusing sexual attraction/orientation with gender identity. The two are different subjects.And without sexual attraction, there can be no gender identity.
Male and female brains are physically different. They are composed of different types of cells and they think with different parts of the brain. That’s one of the reasons that certain types of head injuries affect men and women differently.For a very long time, the words “gender” and “sex” were used interchangeably, but that is not only no longer the case, but also nowhere close to the truth. So… for those who want to progress with the times and embrace the full spectrum of human identity, a common question arises: what is the difference between sex and gender?
To grossly oversimplify that means that some kids are simply born with a "girl brain in a boy body" or vice versa....since sexual differentiation of the genitals takes place in the first two months of pregnancy and sexual differentiation of the brain starts in the second half of pregnancy, these two processes can be influenced independently, which may result in extreme cases in trans-sexuality. This also means that in the event of ambiguous sex at birth, the degree of masculinization of the genitals may not reflect the degree of masculinization of the brain. There is no indication that social environment after birth has an effect on gender identity or sexual orientation.

First a basic fact - sex and gender are not the same thing. People use the terms interchangeably in common speech but the medical and scientific communities differentiate between the two. And they don’t always agree.

As the article points out:

Some laymen may believe humans are more highly evolved than the common house fly. Some entomologist may disagree."Agreed.
It likely is a differentiation in the brain.
But it is most noticeable after puberty I think.
And the other important point is that while DNA is supposed to dictate hormones that effect brain growth, there are lots of reason it does not always work right." R5 #1,094
Adversity driven attrition drives evolution.it does not always work right.
So instead of calling it a "federal penitentiary", call it "penitentiary and debauchery palace". Right?#1,095
It can be argued that the "screw everything that moves and worry about it's sex afterwards gene" is actually beneficial to the species since it leads to more offspring and a more diverse gene pool.The male & female standards play a well known role in species perpetuation. Is there some benefit to non-standards we're overlooking?
