Since I have a BA and MA in English literature, I'm familiar with lib professors. But looking at this article, I don't see anything that tells me this professor was especially liberal, or that her political leanings (if any) have anything to do with this killer. On the contrary, it sounds like the professor cooperated with the police in a helpful way. Did I miss something? I don't understand your comment about "destroying young people."
Some people around here just hate higher education. That's all.
