I disagree because men and women are biologically different from the day of birth.  I know lots of 5'4" women and lots of 6'1" men.  A man, no matter how many hormones and surgeries he has will never be a woman.  Jillian will be a transgendered woman.  I hope she has a fine life and enjoys cycling but Jillian should not be allowed to compete in a women's sport.  The current social climate is driving this.
