I have another wonderful professor this semester. The guy teach poly sci. He opens the first class by asking how many of the students are freshmen (most of them, probably around 4/5 of the class, which cheers him immensely). He talks about how he loves teaching freshmen because he gets to be one of their first experiences in university. At this point, I would normally be thinking something along the lines of "fair enough", but I've been forewarned about him by people who have had him before.
At this point he starts talking about the last Ice Age, edging towards climate change in a truly painfully obvious way, ending on the note of, "Well, now, if global warming is only caused by the Industrial Revolution and SUVs, how did the Ice Age end?" No joke, that's word for word what he said. From there he segued into talking about propaganda, Goebbels, demagoguery, and how we have a responsibility as citizens to see through the lies propagated by the government and media. Followed by him quoting Bill O'Reilly verbatim, apparently from memory, without a trace of irony. If he had suddenly pulled a reveal at the end of the session, I would have called it one of the greatest pieces of satire I've ever seen.
Word from people I know is that the easiest way to get high marks on his paper assignments is to find a way to criticize Obama somehow, because that will distract him from the rest of the paper. One woman showed me one of her old papers where he had completely filled the margins of a page praising her for that, completely ignoring the gist of her argument.
On the flip side, he shot down someone who was advocating cultural relativism as a workable ethical system, but that's small potatoes compared to everything else. I mean, it's one thing for a professor to let traces of their opinions slip into what they teach, but it's another entirely for them to intentionally use the class to actively push their ideology. What happened to unbiased presentation of facts? >.<
