@marlowe1 I’m a political science major, so I’ve taken a lot of classes that discuss politics, but not usually the sort of politics you’re referring to where there’s a clear liberal and conservative opinion - I essentially exclusively did foreign rather than domestic policy classes.
That said, I’ve had a few political philosophy seminars that covered racial issues; the profs treated the right-wing and left-wing students’ comments identically. I’ve never seen abortion or campus politics come up in class. Plenty of professors are openly liberal/anti-Trump.
