So, do we carry a photo ID of our genitals? (Will there be funding for "landscaping"?) Do we drop our drawers for inspection (TSA-like) before entering a restroom or locker room? Blood test? Flash our boobies? What if someone has man boobies? What happens to a person who has no genitalia? Females with beards because of hormone disorders? 
And let's leave churches out of it shall we? Unless we include all spiritual traditions, which of course will only create further conflict. Sorry Jim, but the "Christian church" isn't the only spiritual practice out there. 
Who the heck carries their birth certificate around? 
And now, I've just wet my pants. Sigh. I just wanted to go pee. Middle age sucks.
