Facts matter, Truth matters.  We are all a product of our DNA. XY chromosomes, males, are vastly different from XX chromosomes, females. Humanity requires us to celebrate, respect and acknowledge the differences.  The biological DNA of an individual determines their sex male or female it is that simple. Biological males should not be allowed to participate in female sports because of their physical biological advantage. Both males and Females have a right to their privacy and private spaces. Do not destroy girls' sports by allowing males, XY chromosomes to overwhelm the competition.  Keep biological males out of females' sports.  Those individuals that deny their DNA can start a sports league of their own.
