Some perv will sue to have the doors removed from the stalls...You’re not entitled to your privacy.
This already happened with a mentally ill young man who said he was a girl. They installed changing stalls with curtains so that he could use the girls’ changing room, and the girls could use it if they wanted as well.
The rule was that he’d have to change behind the curtain so girls wouldn’t see his penis.
He sued, saying that was unacceptable. To be considered a girl, he had to be naked AMONG the girls. His so called right to acceptance trumped their right to privacy.
