While it's true that in universities faux-Marxist pseudo-intellectuals have cultivated an intolerant strident Political Correctness that is fatally undermining the ability of universities to deliver much of value, the right persistently over-inflates the influence of such fatuous tenured pomposities in order to promote its low-IQ neo-fascist agenda.
Let's remember what the Republican Party stands for today: anti-science, anti-reason, pro-superstition, pro-authoritarianism, anti-democratic subversion. The US Republican Party is undermining the very basis of civil society. So to pretend that the main threat facing the USA is a bunch of flabby academics spouting halfwit drivel is to be either incredibly naive or incredibly disingenuous.
