I do not care who you identify as or who you kiss, for me it is purely an equipment issue. Each equipment goes to its appropriate toilet (and I am only speaking about lower body equipment here).
You go through the surgery, take the hormones (why would anyone want to?) Then great walk right into the ladies. Otherwise use your urinal.
That's the slippery slope of it. There are already criminal cases of perverts taking advantage of the transgender laws. Will all restrooms be unisex in five years? Or, will people have to carry an ID certifying their gender or "transgender?"
