All institutions, public, private, and communities, have a narrative that favors them. That's not particular to universities.

However out of all the institutions I have personally and anecdotally interacted with, universities have by the far the most openness to dissenting ideas, by a very substantial margin.

A lot of people revel at the amount of internal gossip and conflict within universities, but the fact that it exists, rather than there being people kicked out without question, is a testament to its flexibility.
