Free Speech Article on Slate about the University of Chicago

Another criticism levelled often against colleges concerns the conduct and content of classes: the accusation that Profs push their personal convictions too hard on political matters and shut down minority viewpoints of conservative orientation. I am curious, @HydeSnark or @phoenix1616 , about your experience at Chicago: (1) How often does it actually happen in a discussion-sized class that the subject matter turns into one in which there is an explicitly political or culture-war dimension? (2) When that does happen, and if a dissenting opinion is expressed by a student, how does that get handled by the Prof?
Anecdotes welcome.
