If you want to push stupidity then you'd have to convince the boxing federation for not allowing him to box, but what you're not realizing here is that if you want to push dumb ideas for which 5% of the population might have, then don't complain about Christians wanting a Christian Theocracy.
Because you made the first move so now the rest is in reaction mode of your move. This is how tides of history work.
So if you want to convince the majority that a "woman" who looks like a guy, sounds like a guy, smells like a guy, walks like a guy and is built like a guy is a "woman" then expect the police at your door for checking-in if you're in compliance with your mullet haircut and your ford pickup truck.
