“So, as a guy, I could go to Massachusetts, put on a dress and walk into the Women’s Locker Room at Planet Fitness...or Hooters?”
Why put on a dress. Couldn’t you just identify as a woman who is also a cross dresser?
"What if you’re a man who identifies as a tomboy?"
All of that would be OK, as long as there's no "cutting off" of private parts, or any of that breast-enhancing stuff!
Afterall, I'm just there for the scenery... :-)
