Except science shows that it is a physical condition. Trangenders have both different gene sequences in the NR3C4 and CYP17, and different brain structure in the Stria terminalis
For transgenders it's not all that cut and dry. Behavior can change the brain due to its neuroplasticity. Learning creates new neural pathways, so what you wrote about could be an effect and not necessarily a cause. As the old dictum says, "correlation does not necessarily imply causation."
And different gene expressions code for every mental illness from schizophrenia to OCD that result in unique, dysfunctional structures. That tells us absolutely nothing.
And there has been study whether these people have the opposite gender's brain structure- hint they didnt. NationalReview's Williamson wrote about it at length.
yes, I've actually read 2 of Williamson's pieces on transgendered people (cox and manning), they do not dispute the studies that I mentioned, and have both been highly criticized. In fact, the Chicago Sun Times retracted the op-ed on Cox, issuing the following statement:
A recent op-ed piece we ran online that was produced by another publication initially struck as provocative.
Upon further consideration, we concluded the essay did not include some key facts and its overall tone was not consistent with what we seek to publish. The column failed to acknowledge that the American Medical Association and the American Psychological Association have deemed transgender-related care medically necessary for transgender people.[/i]
So you'll have to understand that some of us dont consider Wiliamson's pieces canon.
And of course, the actual studies are there for anyone who would like to read them without media agenda or editorial, but for pure data
