There's much talk about tolerance these days, but those who advocate tolerance are often unwilling to be tolerant of others, especially when it comes to another's perspective. Nick Kristof, a self-identified liberal writer at the NY Times criticizes the intolerance of liberals on the majority of college campuses. His piece, entitled, The Dangers of Echo Chambers on Campus warns "We champion tolerance, except for conservatives and evangelical Christians. We want to be inclusive of people who don’t look like us — so long as they think like us." Only about 10 percent of professors in the social sciences or the humanities are Republicans. This lack of diversity results in an "echo chamber" mentality, where those in the majority can drown out minority views and this, Kristof says is not healthy for college campuses or the kids they try to serve.
