We are not other animals so they are irrelevant to the point you are failing to make.
DSDs are also completely irrelevant to your definition & have nothing to do with the topic of gender ideology.
Those people are not transpeople, they are just people who have a DSD which is a completely different thing.
Human beings are a sexually dimorphic species.
One half are called women & this name was given to those who have XX chromosomes, the other half are men & carry XY chromosomes.
Humans have not developed mutations that allow them to switch from one sex to the other by the use of drugs, surgery, environmental factors or wishful thinking.
Whatever they do, they remain the sex that was determined at conception.
Gender used to be a normal word that tended to be used as a more polite way of defining the sex of a human.
Now it's used as a fantasy signifier of what some people want to force others to pretend, based on nothing but soft science twaddle.
This intentional corruption of the meaning of a sex based word has been used to try to cloud the issue for the hard of thinking.
It doesn't work.
Just like religion, one can say they are a follower of that belief system without actually changing the reality of their biological sex.
People now define gender as being something other than an indicator of sex, so your gender does not determine your sexual classification.
A biological man remains a biological man & a biological woman remains a biological woman no matter how they identify.
You cannot identify into a sex class.
Hard (aka real) science, where facts matter, continues to prove that Gender, as the word is used nowadays, is a load of unscientific nonsense founded on ideology rather than reality.
Just look at the single pair of chromosomes that are define your sex.
It amounts to approx 4.3478% of your genetic material.
I wonder if you have any clue how massive a difference that actually is?
There is about the same amount of genetic differences between humans & apes are there is between male & female humans.
There is no experiment (that I know of) that can be repeated successfully in a lab to show that this pair of chromosomes which determine sex in human beings who have already been conceived, can be manipulated into changing an X into a Y or a Y into an X.
There is no widespread mutation present in the human gene pool, common enough to be borne by every person who says they are 'trans', that has been identified as being related to what you think of as Gender.
There is a big enough sample with all the shouty people on Twitter etc... that it should have been easy to find if it existed.
Even if there was a 'gender gene', it still would not change the reality of the genetic sex you are at the point of conception.
Leave out the intellectual wankery that defines the soft sciences, even if they have tried to shove in some stats to make it look like real science.
None of it proves anything & it relies on interpretation which is subject to personal bias.
Show everyone your repeatable results that demonstrate this with hard data from reputable research facilities to dispute this, or stop pretending that you don't know the words woman & man have been used for centuries to define the two distinct & immutable sexes in humans.
Reality doesn't care about peoples feelings.
