I've had the fortune to get to know several professors, who were no less than experts in useful fields of knowledge and science, so i can't buy into that generalization.. When that's said, a professorate does not automatically give credibility to any argumentation 'by itself' and if the professor in philosophy in question, really postulated the outrageous stance he's quoted for, he's ethically and morally on extremely thin ice and should be held accountable for it, as it's at least borderline criminal behaviour to advocate for abuse of children..
