In order to get rid of the coonfusion of your education:
"...Speaking of which, I wanted to briefly mention a point. As you all know, I was once a leftist myself -- HEY, WHO ARE YOU CALLING STALIN?!!! -- which it is almost impossible not to be if you are as educated as I once was. You don't even have to think about it, because you simply pick it up through kosmosis by spending so many moons in the rarified error of that lunar 'batmosphere. Eventually your common sense is eclipsed.
It's not just that all of one's professors are explicitly liberal. It's the way they implicitly think about the world -- the problems they notice, the questions they ask, the topics they emphasize, the things they exclude or take for granted, the jokes they make, the things that cannot be joked about, etc.
But if you are intelligent, you don't just leave it at that. Rather, you want to dig a little deeper. This, I believe, is where the gnostic element of (-n) fits in. What makes human intelligence human (and often all-too-human) is our ability to see beneath the surface and unify phenomena on a deeper level. But obviously it is possible to not only get things wrong, but to do so in a systematic way, e.g., Islamism, scientism, atheism, phrenology, etc.
This I think is why leftists always believe such conspiratorial nonsense. In my case, because I knew that there was more to reality than met the eye, I began reading things by Noam Chomsky, Howard Zinn, Edward Herman, Michael Parenti, Eric Hobsbawm, the Frankfurt School of psychopolitical loons, you name it. I didn't even know that these people were Marxists, nor would I have cared if you had told me. I subscribed to The Nation and thought it was actually "objective." I listened to Pacifica radio. I even contributed money to them! How will I explain this to God?..."
