The hands are always a dead giveaway.
The point is transgenders have been using what ever bathrooms they want and no one knows. Are you really going to walk up to people who look like that and say “man hands”??
Have you ever said that to a woman?? I bet not, and that you never would.
Are you going to call 911 and say “there’s a woman with man hands in the women’s bathroom”? I bet not.
