The fact is that trans representation in sports is so small it is statistically insignificant. Further anti trans regulations prove to hurt both trans and cis people. The harm to trans people is obvious in that it bars them from activities they should be allowed to take place in. The harm to cis people is often in the form of being  profiled as trans when they don't abide by  traditional gender norms in clothing and hair styles. In the end this will just hurt people that are  hurting no one.
