It’s so obvious that so many here didn’t even read the article.

This really isn’t about toilets as much as locker rooms. Where each person must go to the gendered locker room for their biological sex. Unless there is an alternative. Such as a “trans locker room”

The whole toilet part is adressed in that most businesses will just remove the symbol for M/F on single stalls and call it a day. And most have a handicap friendly stall, which already is gender neutral.

This is more of an issue for places like hospital’s that are required to have gendered spaces.
