I hear this a lot, but I graduated from a US university and I never knew how any of my professors stood on political matters (and I was a hardcore conservative in college). Right-wingers tend to be upset that social sciences and the humanities exist as research topics and degree programs, mostly because they're not happy with study results that run counter to their beliefs.
Which is also silly, because if they had conversations with those professors, they'd mostly find people with extremely nuanced, evidence-backed opinions.
It doesn't take too long in research-land to appreciate that ideologies are merely abstractions; they're tools to help us understand and discuss the real world.
The people with blind ideological faith are mostly uneducated (and perhaps undergrads), but the academics know how messy the world actually is and love to talk about the jagged, contradictory bits that don't line up with our current models of thought.
