Yes, all those slave-owning Greeks and Arabs were really the pinnacle of open discourse and the pursuit of enlightenment. There was definitely no social model they intended to enforce on others, and their universities were bastions of openness. Truly.
There is nothing "post-modern" about this either. My ideologies are as modernist as they come, and it's clear to me that the ancient Greeks were in no way in favor of some platonic ideal of open, free discourse. They didn't let allow women or slaves in their open, free discourse, and even if they did, but shouted them down (as antagonists of safer spaces are doing in this thread, the University of Chicago, and virtually every other space, because oppression is the default, liberation is something you have to actively build), that would not make the discourse any more free or open. You're not being "anti-postmodern," you're just being willfully blind of savage inequities in the institutions you're holding up as examples. If you didn't want that contradiction examined you shouldn't have spoken up. (And don't even think about complaining about being called out for this -- what do you want, some ``safe space'' where you can just pat yourself on the back with other slavery apologists?)
Many people do not agree with that and not just reactionaries. A majority of philosophers (natural + unnatural) and religions in history would have explained their world by cycles. There are a great many events, many disturbing to the happy-go-lucky narrative that the Progressivism Forever hypothesis fails to explain.
I take the point that Cthulhu swims slowly leftwards but without understanding why it is that he does so it is dangerous to extrapolate for the next 300 years.
Sure it was. In the 1960s and 70s, for example, when Universities were a hotbed of free speech and civil liberty activism:
It is true that there were significant student protest movements at many universities in the 60's and 70's.
I don't think that this invalidates the OP's point that "historically, a major function of universities has been being places where white male elites could congregate and maintain their power by excluding others".
Look over the last 200 years or so of universities in the US. It's only since the 1950's that non-whites and females started attending in significant numbers.
Even if we take 1970 as a cut-off where that is no-longer the majority case, the OP's point is still valid.
Take, for example, the Yale Halloween controversy, where supporters of this ideal fought hard to protect white male students from the idea that their costumes were mocking others because it might make them uncomfortable wearing them, and that violated their free speech somehow.
Or take the conservative activist who was so outraged at a left-wing poem in a newsletter that he barged into the office of a professor involved with it, demanding to know who "approved" the offending article and refusing to leave, and how groups like FIRE and all the other vocal supporters of the free end open exchange of ideas insisted his actions were a valent stand for the freedom of student speech.
That's an ideal that was never really true. Historically, a major function of universities has been being places where white male elites could congregate and maintain their power by excluding others: http://www.businessinsider.com/the-ivy-leagues-history-of-di....
I'm not a supporter of the movement to stamp out uncomfortable ideas from universities. But let's not look at things through rose-colored glasses. Even with space spaces, universities today are much closer to the ideal than they were 50-100 years ago.
