Fetuses Socalized in Womb to Exhibit Male or Female Brain Gene Expression

We don't know anything about how a mind is created or what it is, except our subjective experience of one mind.

We do know the obvious.

A brain is not a mind.

What we know is that the mind is a byproduct of the brain and that everything about the mind and subjective experience can be altered by altering the physical brain.

The mind is created by brain activity so a change to the activity can change the mind.

And as a person ages the brain itself changes and so does the activity.

But the activity of the brain for most is very stable and only changes very slowly over time.

Psychological gender is an aspect of the "mind", and like all aspects of the mind, it is a byproduct of the physical brain and thus a result of interactions between genetic code and environmental factors, which includes fetal hormone exposure that shape development of the many brain features that are both shared and highly vary on average between the biological sexes.

A lot of gender identification is cultural and has nothing to do with the brain

Long hair in some cultures is feminine while in other's it is masculine.

A dress in some cultures is feminine and in others masculine.

However, contrary to the OP, this science does not undermine the biological foundation of transgenders nor does it support a binary conception of gender. The differences between the sexes are on average with huge variations along a non-binary continuum around each average tendency, such that a large % of males overlap with a large % of females on these measures of gene expression and brain features. Plus, there is science showing that fetal development of the genitals and of the brain regions involved in psychological gender occur at different time points and thus have different In-Utero factors impacting them. Which makes it not only plausible but likely, that some % of fetuses will develop brains (and thus psychology or "minds") that are more like the brains and "minds" of typical members of the opposite sex in terms of chromosomes and genitals (not even considering the % of babies with genitals that cannot be categorized into a binary system).

Yes.

The heterosexual never chose the idea of finding a mate of the opposite sex.

Nobody chooses their sexual preferences.

Although I think being sexually attracted to children is more about wanting to control another for your selfish use, about the "ego", about greed, than merely about a sexual preference.
 
The are angry people of every stripe.

A lot of angry white males.

They lifted Trump over the top.

The activity of every brain is changing constantly every second, and every time your process a piece of information is changes how you will process related information in the future. When you recall an event, there is a neural activation pattern associated with that act of recall. But a single act of recall causes slight changes to the brain which will alter the pattern of activation next time you try to recall that event, and thus will change your mental subjective experience of recalling it. Your brain (and thus mind) are changing constantly).

Everything to do with the mind is a function of the brain. Information in the environment only impacts the mind/gender by impacting the brain in ways that alter how the brain responds to future stimuli. All cultural influences on the mind are mediated by changes to the brain.
And while culture does impact the brain and thus the mind as it relates to gender, there are also large differences in countless aspects of psychology and behavior that are rooted in non-cultural/non-informational physical impacts on the brain, which includes how chromosomes impact gene expression and hormone effects on how the brain develops In Utero and during puberty.

Just because there are outliers doesn't mean gender is not binary. Some people are born with six toes or three nipples or double dongs. The whole point to gender is procreation. Nature doesn't care about our feels.

It isn't a matter of "outliers". It is a matter that all males and all females differ from members of their own sex and vary on every dimension along a continuum. When there are differences between males and females on average, it still means that a huge % (often a majority) of humans fall along a continuum between those means, typically with a large % (up to 49.999%) of one gender falling at or above the mean for the other gender. Look at the actual data in the gene expression article you cited. The distributions for men and women are almost entirely overlapping, with gender accounting for very little of the total variability.

Put it this way. Take one these genes that show a "sex-bias", which simply means that there is some non-zero difference in the average degree of expression in that gene between males and females. IF you simply had information about the expression of that gene for a person and tried to use it to predict the person's gender, you would only do slightly better than random chance in your predictions.

The brain changes slowly and there is no evidence that one experience unremembered changes anything. We have thousands and thousands of experiences everyday. Most change nothing and most are not remembered.

The brain is not a blank slate so easily written upon. It changes only as it was designed to change.

Traumatic experiences can over time change the brain. If the person relives them over and over in their mind. like repeated practice of some task can over time change the brain.

When you recall an event, there is a neural activation pattern associated with that act of recall.

That is a current hypothesis that is far from proven.

But a single act of recall causes slight changes to the brain which will alter the pattern of activation next time you try to recall that event

There is no evidence of that.

The human personality, an incredibly complex combinations of features, is relatively stable for a lifetime.

Change is hard and there is good reason for that.

You don't want to move around so much that the important things get confused with meaningless trivia. When you learn to avoid some plant because it made you very sick you don't want such a dynamic changing system that the next time you encounter the plant you forget what you have learned.
