You're still being blind to everything else that happens as a precondition to auditing students making advances to attractive students, if you think that > That's just a different way of saying "People who don't get dates get hurt and angry". We already know that. Perhaps I should spell out one aspect of it. These auditing students have to survey and evaluate the female students taking the class for their attractiveness. It's uncomfortable and distracting to receive such attention when you are in an environment that's primarily for academic learning. Now, I'll admit that perhaps this is only mildly uncomfortable. But as I said in my original comment, the likely result of students taking things into their own hands would be to just take a less preferred course that they feel more comfortable in with respect to sexual attention.
