My point exactly. Making distinctions other than "People with Genitalia A dress here, people with Genitalia B dress here" IS social experimentation. Making exceptions based on anything other than the most basic biological guidelines IS social experimentation. Girls go here, guys go there. End of discussion. We don't care who you prefer to look at naked - you've got Genitalia B, so you go there. Making others uncomfortable doesn't factor into it in the least. Removing this girl because other girls are uncomfortable is just as ridiculous and liberal a concept as disallowing the word "Christmas" because it makes non-Christians uncomfortable. Feelings have nothing to do with it. She's a female; she dresses with the females. For either side to make any sort of distinction based on sexual preference is counterproductive to focusing on academics only.
And, again off-topic - see how I managed to make it through the entire post without some ridiculous bon mot like "Get it?" or "Go sit in the corner"? You might want to try it - you'll look like less of a self-important jackass.
