The issue is not just happiness, there are other reasons why universities are a prime target.
At first glance, Ms. Schlafy appears to be under the impression that the 'weird' and 'left-wing' professors indoctrinate their students into a morally corrupt mindset by their 'worthless and psychologically destructive courses'. She is, of course, misrepresenting the way universities work -- the point of university education is not to just dump some pre-existing knowledge and values on the poor kids, but rather to teach them to think for themselves and be critical. This requires that some of the classes are in fact controversial to a degree, and this in turn requires that the professors are given enough slack to do research and teach classes that do not always conform to the general consensus (whatever that happens to be at the time).
Of course, this is just what she appears to think. Looking a bit deeper, it seems likely that she, like so many ultra-conservatives, is deathly afraid that the great masses learn to think, not just follow what their great religious leaders tell them. Whether she has admitted this to herself is not altogether clear, though.
It's kind of funny, though, that womens' studies and especially the more radical forms of feminism were among the few subjects I never got to grips during my student days. Lately I've come to the conclusion that this is mainly because there is often a tendency to see gender as a conflict between two extremes, and for reasons that should be apparent by now I'm caught somewhere in the middle.
