Her story is suspect IMO because she says....(from the link)
"From my earliest years, I was always different from the other girls. I wore boy clothes, and I played with boy toys. I was a classic tomboy."
"As I got older, I became romantically interested in other girls. In fact, with the exception of one guy I dated in high school, I exclusively dated girls."
There is not enough details like, what made you think wearing 'boy's clothes' made you a homosexual? Plenty of women wear jeans and shirts. That doesn't explain anything.
My retort.....If you got romantically interested in other girls then you became an outlier in society because the vast majority of females are attracted to males....(the opposite sex). Obviously something went array with your normal genetic programming.
I don't recall her saying she thought wearing boy clothes and being a tomboy made her a homosexual. Seems like she did feel like it made her "not right" as a girl, which is silly. One of the things I dislike most about this "transgender" fad is the way it erases the entire long struggle of women to be viewed as complex, unique individual humans rather than just a bunch of shallow stereotypes, which the "transgender" fad is now reinforcing as THE definition of "female".
Seems to me like her real problem was that she had some self-esteem and identity issues. Because no one in her life bothered to identify them and help her deal with them, she went to the Internet and pop culture looking for answers, and found the wrong one.
Agreed, that being said, I do think a lot of the ones making her feel 'not right' for being a "Tomboy" could actually be other females. A lot of men actually like women who enjoy sports, wear jeans, etc. so I don't think it was men making her feel that way. As far has her being attracted to other females, like you said, that is another issue. Could be genetic, environmental, abuse, etc. As far as 'complex' goes, all I can say is I still have yet to figure out my wife after 40+ years of marriage. She, however has got me down to a 'T'....Not sure how that works.
