Much ado about nothing!

How are you going to enforce a ban preventing transgenders from using whatever toilet they want? Look up their dresses? Some women appear rather masculine; some men are rather feminine to begin with. Add make-up and who knows. Adam's apple examinations? Also does not always work if this person had had surgery and/or various hormone injections.

There is little practical consideration here just a religious based fervor which also looks very much as having little to do with the Golden Rule of doing under others as you would have done to you.
