Should gender be determined by natural hormone level rather than genitals?

@taehyun The human idea of physical sex doesn't change based on what you identify as. Gender does change if you identify as something. If you have two X chromosomes, breasts, a vagina, and the ability to carry and birth a child, you're a female. If you have an X and a Y chromosome, a penis, an Adam's apple, and the ability to impregnate a female, you're a male. You can identify as a fucking Fruit Roll-Up for all anyone cares and it won't change your sex. Your gender, however, I guess is different. That's when you might feel you're somewhere in between male or female or you're an androgyne or you're something else.
