Suppose you went to your local athletic facility where there was a swimming pool, basketball court, etc. Suppose you took your daughter into the women's locker room and were getting ready to change to go into pool...
Suddenly, a naked person walks into the main area from the showers who has a penis flapping between "their" legs.
This person claims they are a woman.
Is this okay? Are little girls supposed to be allowed to have to be exposed to adult male genitalia in locker rooms?
Nope!
