Academics are often bafflingly stupid, though this isn't always necessarily left wing, just predominantly. A few years ago anarcho-capitalism had a strange degree of following with a few educated people despite the fact it blatantly doesn't work (good luck making a country with no army and no borders), resulting in stupidity like Galt's Gulch Chile. Fortunately that has largely faded away now, but I had someone with postgraduate education tell me that he used to be an anarcho capitalist before he realised that having a lawless, borderless waste for a society possibly wasn't the best idea.
