I am well aware of every argument you raise. I run into them frequently. And for the most part they are always presented as a way of defending a person’s right to be who they are, with which I do not disagree. My point is that the research is becoming clearer every day that there are in fact differences. The correlation is not 100% because not everyone is binary. What I am looking for is a way to establish legitimacy in the mind of the skeptical public. I do not understand why some resist finding an objective basis to establish our authenticity. That just perplexes me. Your arguments play into the attitude of people like Matt Walsh that being trans is just as deluded as saying you identify as an attack helicopter. It makes about as much objective sense to someone who is skeptical of the validity of the trance experience.
As to your first point, I firmly believe that it will be proven that it is the dysphoria that causes the brain anomaly, not the other way around. On what possible logical basis could you think otherwise? As to people having dysphoria and that is what causes them to be trans, it must have a common origin of some type. What exactly is it? You ignored the question and you put over emphasis on genitals because they are easily observable. The brain can also be observed but only with advanced technology. The fact that one seems so certain to you and the other more mysterious does not make my comment inaccurate. Trans brains are just as much of a fixed biological sex characteristic as genitals. Indeed I would say that they are more important because that is the seat of your self-awareness and identity and cannot be changed. Bottoms can. Nature and nurture are involved in the development of everyone trans or not. But not all possibilities are open to every individual. What we start with in many ways directs how the plasticity of our brain changes and the way we develop. Even very young trans children know they are when there is no influence from their environment that would’ve suggested to them that this was their identity. It is instinctive. This cannot be ignored.
To say that the area is still developing and that there are variations is no different than saying that there are many men with female facial characteristics and women with male characteristics. This is evident upon close examination. But there are general groups that most of us can identify. You use the exceptions to try to delegitimize the general rule. The research is being done and I think you will be surprised at what is finally firmly established. Your arguments are the kind of gooey messy unconvincing ones that are not useful to anyone but the trans community itself. You will never convince the trans phobic and the skeptics. That is my focus on what I am trying to accomplish—the methodology to do so
