It's already had an impact. And it's just beginning. How much unfairness is acceptable? "Oh, it's only harming a few". Is the NCAA there to promote fair competition or to enact liberal social engineering policies?
I find it weird that you're willing to rationalize this crap and disregard individual rights. On second thought, if you're a leftist you're more about the collective, so it makes perfect sense. And no, you have no right competing against women if you were born male, chem treatment or not. Your DNA, bone, and muscle structure cannot be completely changed. Science dude.
