lol! If example d.) in the green panties and red heels came into the men's room while I was using it I would exit as swiftly as possible.
I agree with your premise, how the heck are they going to enforce it? There is such a thing as a probable cause requirement to ask for ID, and clearly a passable or blendable crossdresser could make a good argument that the charge should be dismissed for lack of probable cause. Sort of the same idea about which black people complain for being pulled over for "driving black" when they had committed no traffic violations.
To monkey wrench the thing, maybe we TG's could organize a posse, and hang around ladies restrooms and when we spot some poor hapless woman who is wearing jeans, a sloppy sweat shirt, and a baseball cap blow the whistle. Or, just some woman being fashionably Butch. The attached foto is of Annie Lenox, famous rock singer. images3622MWTH.jpg
