Maybe for the most part. But they do allow some radical elements. I took a class in college called Global Inequality, that talked about slavery, colonialism, and neoliberalism, and that had a somewhat large class size and counted for a 'diversity' graduation requirement. It definitely radicalized me more and got me really angry. I took another class on the History of the Modern Middle East and the professor was one of those classic young Marxist dudes. I did also take an International Relations class that was taught by someone who did foreign relations for NASA though lol and she basically repeated the "sweatshops are good for poor people" lie.
