Yes, it is sad and unfortunate when biology and genetics aren't in sync. I'm going to assume she has a vagina, which is likely the reason she was labeled a female at birth. The rest of her physical appearance (breasts, facial bone structure, etc) certainly appear to be male, along with presumably chromosomes and testosterone levels. It sucks, but this is where empathy, IMO, is a weakness and leads people to do the wrong thing. The wrong thing is allowing a male, in the ways being a male matter athletically, to beat up on females.
Surely a vagina doesn't supercede all other sexual characteristics.
