so since you like to complain about this so much, what is your solution? Are you just going to ban XY individuals who expressed female biology from birth? Ask them to compete against men? Or just exclude them, divide humanity into haves and have nots in just one more way?
"It's not fair they have an Y chromosome", OK, what about an XX girl born 6' 4" playing in the WNBA, is that "fair", most woman are not that tall - is it fair. What about Yao Ming, he is about as rare a male specimen at 7' 4" as an XY female is, should he have been banned from the NBA because he was 'unfairly" tall. I'd guess fewer than 1 person in a million is born with the combination of hand-eye coordination, strength and neuro-conduction speed genes Miguel Cabrera was born with. Clearly a genetic freak that should have been banned.
In the final analysis, the whole basis of athletic competition is sorting people out by how lucky they were with the genetic set they were born with, and virtually every high level champion is a genetic freak at some level, so how do *you* decide which kinds of 'lucky' are less acceptable than others?
