Accepted him ?  What about the last girl who didn't make the track team and had to stay home and was denied participating  because that spot went to a boy ?  What about the girl who finished fourth ?  She was there to race against other girls , not a boy.  This isn't an issue over life choices , but an issue over fairness in sports.   In today's sports we go out of our way to make sure athlete's don't use performance drugs giving them an unfair advantage over those they are competing against . A boy running against a girl is the greatest advantage possible.   And we are willing to lower our standards of fair play to accept that ?   That's not hope for the future , it's the opposite .
