If the comments at YouTube are accurate, he's a lecturer (not a professor) at UC-Irvine. He's the smug type that might think he's bright enough to succeed in the tenure track, but his productivity, even at UC-Irvine, isn't near enough. Most students wouldn't know the difference between a lecturer and a professor of course, and spending 5 minutes to advocate a political position in a biology class is incredibly arrogant (and lazy - he should be teaching the course). Imagine the outcry if he did the same criticizing our weak border control and sanctuary cities for illegal immigrants.
I had a History professor once who would wander in 15 minutes late, spend ten minutes lighting his pipe, then ramble on for 1/2 hour about how you can't buy a decent pipe in America...he buys all his pipes in Paris... we should all spend as much time in Paris as possible...He's writing a book in French because nothing written in English is worth a damn...
He spoke three languages: Magyar, French, and German. But not English.
