This is such a non-story. The content of those emails is really really tame. Go read totalsororitymove.com or totalfratmove.com and you'll find equal levels of college drunk hookup culture openly displayed. Or go read textsfromlastnight. Young people say things in some contexts that they wouldn't in others. I bet you can find old usenet posts from currently respected senior people in all sorts of fields that are equally troubling, and these posts weren't written for public consumption.
More importantly the email leaker is quite the jerk for releasing them. There is no smoking gun here, just some moderate embarrassment for a moderately famous person.
