No, the people who do the actual neuroscience research on the topic think not.
Sigh. Tsk tsk. You didn't read the literature review I linked:
NO, I read it. Go back and look at the quality of the evidence, note the descriptive words used to describe it.
Irrelevant however.
The DNA of every cell reflects the birth sex of an individual, except in extremely rare cases.
So, if all a criminal investigator had of a murder victim were brain cells, She could absolutely determine the sex of the victim by the DNA in the cells.
It is always the same re research of sexual dysphoria. There is no homosexual gene.
Other attempts at determination are described as , could be, might, seems to, perhaps, etc.
People are free to live their lives however they chose. They could identify as a turnip, their right again.
As to trans gender folk, I think their very name, trans gender, says much. Gender is a social construct, it has nothing to do with scientific sex identification. They have not changed their sex. It cannot be done, regardless of surgeries, hormones, suppression drugs, etc.
Once again, their absolute right.
However, when I see a guy, in a mini skirt, who needs a shave, and has knotty, muscular legs, with huge feet, who walks like a man, I see a man.
I knew one fellow, who was married and had three kids, who did the transgender thing. He continued living with his wife. He didn't look like a woman, but he tried. When we visited, I would always ask him if he was a lesbian, and he would crack up. I gave him respect as all people deserve, and we had good conversations, yet I knew he wasn´t a woman. I never talked about that at all.
