Why is everyone getting their slip all ruffled up over this?
Look, just as the political parties and lobbies have litmus test to assure of a persons intentions, we can solicit the same mindset to this issue and be done with it forevermore, you know, like move onto more pressing items
If a "person" of any gender can stand up and still pizz in a urinal, its good to go.
If not, sit down and wipe this off your agenda!
Next problem.....geez.
