This article did get me thinking about what it is that secular institutions such as public schools and universities do stand for. Is there anything beyond competence in subject matter? I think there is very little that would get one censured or remove from a post unless the activity were illegal. That's a fascinating thing, really: secular has come to mean all is permitted unless it is illegal. Thus, in theory, if bigamy were legalized (and with the push for gay marriage, it is difficult to find grounds to argue against bigamy), the bigamist would have as much job security tenure as anyone else.
Beyond these moral questions, the deeper question is, "What do institutions of learning stand for?" Hmm.
