True, being tall does not make a woman biologically male. I’ve known many tall cis women, including my own grandmother.
However the woman I am referencing is my comment (my girlfriend) just so happens to be a tall trans woman, and thus biologically male.
I made that comment to demonstrate to another person on the thread that being tall and trans is acceptable to people such as myself. I made it to show support to trans women who happen to be tall and might feel self-conscious about it. But true, many tall women are cis.
