Look man...you can not explain athletics to individuals that do not understand athletics.
The most obvious and serious thought is understanding that sports minded females who alter themselves to men.... do not compete in men's sports. But sports minded men who alter themselves to women "DO" compete in women's sports.
Of course..there is a reason for that. Any time one makes a change in their life-there tends to be consequences. It's your choice..so deal with it. To be specific..if you are a sports dude and are transitioning to becoming a women....welp...you should still be competing with and against men. It's really a stupid fn' discussion void of common sense.
