Many of their arguments and actions are fundamentally
illiberal, though, which is why I don't really consider these people all that liberal. They're "progressives", not liberals, and historically progressives have been all too happy to turn authoritarian to accomplish their goals with scarily similar tactics to the conservative establishment that the counterculture that was born out of colleges and universities rose up against. Remember for instance that the prohibition movement had s**tloads of overlap with the progressive movement, who believed that alcohol was a very male social ill destroying families that needed to be stamped out.
How they act in their spheres of influence is enough to tell me I want nothing to do with them because they are very definitely
not liberal-minded. Shut down
this campus newspaper, don't utter
those words, people should have the right to opt out of school curriculum if it upsets their delicate sensibilities, don't allow people we disagree with to speak at our venues, extra-judicial arms of the university that throw people out for the slightest of excuse, no trial necessary, everything is problematic and things being problematic is problematic. Season to taste with incorrect statistics and hypocritical cultural relativism.
Those are not liberal, free-thinking ideals. Those are the sort of things campuses rose up against, and provided the backbone of the free speech movement that fought against obscenity and revisionism. That buoyed people like George Carlin, who would likely be disowned by many student activists today. That they've made something of an enemy out of the ACLU nowadays speaks volumes.
