There should be bathrooms for heterosexual XY males and bathrooms for heterosexual XX females.
The perverted can do whatever they want as long as I don’t have to know about it.
A better idea: since the Left like to throw "science" in our face as an answer to everything, start labeling the bathrooms XX and XY. Regardless of how one identifies one's gender, you literally can never change the orientation of your chromosomes.
Heads would explode the world over.
