Circling back to this dead horse again? Listen, some cultures don't even let same genders change in the same room together because it's gross. You assume that's a general rule but it's not. There are many people who don't want to change in front of anyone. So instead of outlawing separation I say we go in the other direction and make it normal not to change in front of anyone regardless of gender. Now find a new subject to disgust the rest of us with because we're getting bored of this one.
