She has to take external testosterone to even compete with a male, and no matter how good a female boxer this abhorrent abomination of she-he is, she-he will never rise to the top of the male boxing world.
She does not have the bone density that only males get when they hit puberty. She does not have the lung capacity a biological male has. She does not have the larger heart a male has, nor the larger organs like liver and kidneys a biological male has.
She won't be able to take a punch. She will not be able to fully compete against someone equally committed and determined as her. She may be stronger than any female when she is on steroids, but she will not be stronger than a biological male with an identical diet and training regime.
Sorry Skippy, there are only two sexes no matter how you EvilDimTards try to blur the lines.
