The truth is, there has never be a documented case of a TS/TG person harassing anyone in a rest room in any way .
A TS/TG person just wants to "do their business" and leave.
However, it's actually the TS/TG population who has often been harassed in restrooms and this has be often been documented.

This stems from the erroneous belief that being gay TS/ TG is a conscious choice that people make..... born out of pure sexual perversion that they have .
So, they believe that any gay TS/TG person in a rest room must be up to some sort of perverse sexual action.
Some ignorant people actually believe this and some politicians are just taking full advantage of their ignorance .
Consider this.... African Americans were once bared from white restrooms using basically the same argument that they would harass whites and "decent people" do not want them around.
