The right to play sports is an important part of growing up in America and an integral part of our culture.  The inclusion of trans women in sports in no way has the potential to harm anyone and only seeks to provide opportunities in sports where someone can be comfortable.  I know that its scary to think about all the big 300 pound muscular trans women who are dominating women's sports right now but if you open your eyes and look around you'll see that this simply isn't the case and the vast majority of trans women and trans men want to play and compete in sports with their gender, which is whatever they identify as.  This has no negative affect on the integrity of female sports, which are already severely underwatched and neglected compared to male sports.
