I would like to point out that the insistence that there cannot be a difference between male and female brains is also a defensive and reactive belief.
Right, but I don't think anyone is insisting that. For one, it's blatantly wrong. If we define sex as gonadal sex, for example, then sex hormones can have a large impact on growth, including growth in the brain. Again, obvious example: "male" brains (i.e. the brains of people born with testes instead of ovaries) to be slightly larger, on average.
However, knowing this to be true doesn't equate to knowing whether it is
important. Brain size was, in the past, considered absolutely critical to intelligence and formed a major part of the argument that men were naturally more intelligent than women. We now know the impact of brain size on actual intelligence is extremely small and that the differences between men and women can be effectively disregarded. Why do other differences which may or may not exist have to be accounted for?

It has been suggested in this thread that trans people insisting on inherent gender is hypocritical because it opens the door for discrimination based on assigned gender. If that is the case then insisting on non inherent gender is equally hypocritical because it opens the door for discrimination based on identity gender.
What you have failed to understand perhaps is that the most important question, the underlying question for those of us who are skeptical of "male and female brains" is
why we are talking about them now. We are talking about identity, a property of human beings which is only intelligible on a social level, and yet here we are having an argument about incredibly tiny differences which have been
claimed to exist in the brain. Why?
The answer is because this whole idea that this whole idea that biology is destiny, that who we are socially and personally is determined by anatomical variations in our bodies, is the original assumption of the two you have pointed out, and at virtually every point it has been wheeled out to defend some form of natural difference between people, whenever it has been wheeled out to justify treating people differently or assigning exceptional status to some over others, it has turned out to be wholly and completely wrong.
The argument that the brain is too complex for us to understand is true, but also increasingly not true, and is certainly not true in the field of anatomical research. Just over a hundred years ago when some Darwinists were still claiming the neurological differences between men and women were so utterly, staggeringly enormous that they couldn't even be considered members of the same species, this idea could survive because actually observing the brain was hard. Today, we can stick someone in an MRI scanner and see the whole thing in complete detail, and virtually every part we can see exhibits a degree of natural variation which is largely unchanged depending on whether you are looking at a male or female brain. The kinds of differences which sexual difference researchers are coming out with today are literally too small to be seen with the naked eye or picked up by an MRI scanner.
Sexual difference has always been the sea monster on the edge of the map. It's been the thing which everyone swears exists but gets further and further away the more the blank spaces of the map are filled in. At what point do we give up and simply stop trying to find the sea monster?[footnote]And no, that doesn't mean we stop trying to find what actually is there, but when do we stop assuming it's going to be a sea monster.[/footnote]
The search for sexual difference was
always political. There was never a golden pre-feminist era when sexual difference research was about "objective" knowledge and nothing else. It has always been about the need to explain, defend or justify a given social (and political) situation, because without that there would be no point doing it (at least, not in the way it's always been done). In this sense, our incredible understanding of the brain (which is incredible, compared to a hundred years ago or even fifty years ago) has come about
in spite of sexual difference research, not because of it.

There has to be a physical difference that results in the mental difference. There is no possible way around that point. The very existence of trans people and the real and documented pain many feel insists there must be something about a brain that can be gendered.
No, it absolutely doesn't.
I'm sad right now because my cat died the other day. That doesn't mean there must be a part of my brain which tells me I'm supposed to have a cat.
I suspect some people are going to find this analogy offensive. I don't mean it as such, I'm merely pointing out that there is a distinction between cognition and neurology. Just because we think or feel something doesn't mean there's any reason to believe it's inherent to us, even if it's very deep seated, very real and very impossible to ever change, even if it's a core part of our identity.
Sexual orientation is a core part of many people's identity, yet I can guarantee that the vast majority of those people were at one point sexually aroused from being wiped during a nappy change, and it likely made absolutely no difference who was doing the wiping. Whether we are born with innate tendencies is an interesting question, but we aren't born with thoughts or concepts, not even about ourselves. Thoughts aren't something that is "hardwired" into our brains.

We know that the human brain has a map of the body, a sort of virtual representation of what the body should be and what kind of feedback the brain should be receiving from it.
In a sense, yes. This "map" develops over the course of our lives, however, and is in no way inherent to us. There is no single part of our brain specifically responsible for storing or retaining it. Furthermore, it's never something of which we are consciously aware, at least not until we lose a limb.
Again, a newborn child can't even recognize itself in a mirror. There's no evidence it has any sense of self or personal identity whatsoever.

But that doesn't matter because I am not trying to say that is how it actually works, I am just trying to make a point here. If we stop and remember that the brain does more than one thing the seeming clash is very easy to overcome. We need to stop thinking of the nervous system as the pile of cells that we think with. This oversimplified view is causing division between people that should be allies.
We are allies. I don't see any problems with that.
