I don't understand your point here. In a co-ed dorm with co-ed bathrooms, we were around dudes way more masculine with no issue. This was in 1992! This wasn't some democrat agenda shyt. This was Virginia, which was really red/conservative at the time, and no one cared. But now all of a sudden it's a political issue? Explain that...you can't. It's all bullshyt.
What y'all don't understand is that when you have to pee and shyt, no one wants to be around you. I promise. You have stalls, and in gender neutral bathrooms, there are stalls around the urinals as well. Usually, they are floor length, so that there is no space beneath the door, because no one wants to smell or hear you do your business. Also, look up the stats for rape and assault in co-ed dorms, and they are actually LESS than they are in other dorms because people who select to be in those environments really just want to be left alone and be around people with no drama. I mean, this rhetoric may work on someone who has never lived in a co-ed situation, but not on someone who actually was in a gender neutral environment for three years.
Also, I visit the gym five days a week. I NEVER look at who is walking in the locker room and who is changing. That would be weird shyt. As a straight CIS woman, I don't want to see other naked women coming out of the shower or changing next to me. So I don't look, and you know what, when I glance up, everyone is averting their eyes, and focusing on their locker or their own shyt. That's a human thing. Humans do not want to be in any setting with other naked strangers just hanging out and staring, regardless of gender. We go into the locker room, change, shower, and we bounce because most people who use a gym locker room have places to go afterwards. This is not a Varsity Blues TV show where people are socializing and hanging out with their ass out. It's a locker room for grown ass people who don't know each other, changing as quickly as possible so that they don't have to be naked around ANYONE. Y'all are the ones making it weird because the assumption here is that if these were all straight, CIS women, somehow they would be free to just hang out with their ass and t*ts out longer, which isn't even a thing anyone wants to do. So yeah, I don't get any of this, but then again, I've actually lived and used bathrooms with other genders so I know a lot of this fear isn't based on reality.
