<p>I joined a co-ed fraternity in the 1970s, and met my husband through it (he had already graduated before I joined). Some chapters at other colleges remained all-male, and they tended to be more misogynous. There were several unpleasant incidents where they behaved badly during visits. I think some of the most egregious episodes involve young men - often athletes - who have been led to believe that they are entitled to get away with anything on account of their unrivalled AWESOMENESS. The Deke bros who marched across the Yale campus chanting “No means yes; yes means anal!” weren’t stupid. Most probably grew up in affluent, sophisticated households where the women are educated and, in many cases, professionally successful. They are accustomed to getting a pass, on account of their status and abilities, and never once thought that they might be slapped down for objectionable behavior. I can’t imagine that anyone bright enough to get into Yale nowadays considered that chant witty and clever. No, they knew just how obnoxious it was, but believed that anything they did and said would be accepted because they were the ones doing and saying it.</p>
