Unrealistic
Never once, in my entire educational experience, did I encounter any teacher or professor who said God is dead or tried to otherwise convince myself or my fellow classmates that our personal beliefs are wrong or we should not have them. Quite the contrary, we always were simply educated on what is known, proven, verifiable, and/or scientifically sound. When it came to faith, well that's up to another institution to teach called church.
The only ones I know of who proselytize faith and use religious absolutism are theists. Perhaps that is why so many of them see secular education as doing the same. Because they are so concerned with every facet of life reinforcing their religion that when they sit in a class room that doesn't proselytize their beliefs they actually see this proselytizing absence as a direct challenge to their beliefs.
Republicans are a party of bad ideas and the Democrats are a party of no ideas. Or other way around?
