Bathroom doors dont have he, she, him, her, they, them, or any genders whatsoever.
The word "man" or "woman" is on the door.
Learn the difference between sex and gender, Dorothy. Its pretty simple.

Just use whichever bathroom you feel most comfortable in and if you are using the bathroom, mind your own damn business and chill out. People just gotta shit.
I really dont know what the big deal is accept when it comes to minors.
Any problems that could arise involving children and bathrooms already exist and desegregating them wouldn’t make them any worse. It might actually make them less likely to happen cuz 1. there will be more people in said bathroom at any time and 2. No matter what the gender of the parent, they can go in the same bathroom with the child.
