A quarter of a century ago, America was already a bitterly divided nation — especially on matters of religion, culture, morality and politics.

Thus, liberal theologian Harvey Cox of Harvard Divinity School (author of the ‘60s bestseller, “The Secular City”) was shocked when he invited to lecture at Regent University. It’s hard, he noted in The Atlantic (“Warring Visions of the Religious Right”), to titillate his sherry-sipping colleagues in the Harvard faculty lounge, but accepting an invitation to invade the Rev. Pat Robertson’s campus did the trick.

Cox was pleased to find quite a bit of diversity at Regent, in terms of theological and political debates. He was welcomed, and discovered lots of people testing the borders of evangelicalism — other than on moral issues with strong doctrinal content. He found Episcopalians, Catholics and Eastern Orthodox believers.

Politically, too, the students and faculty members I met represented a somewhat wider spectrum than I had anticipated. There are some boundaries, of course. I doubt that a pro-choice bumper sticker would go unremarked in the parking lot, or that a gay-pride demonstration would draw many marchers. But the Regent student newspaper carried an opinion piece by the well-known politically liberal evangelical (and "friend of Bill") Tony Campolo. … One student told me with obvious satisfaction that he had worked hard to defeat Oliver North in the Virginia senatorial contest last fall. If there is a "line" at Regent, which would presumably be a mirror image of the political correctness that is allegedly enforced at elite liberal universities, it is not easy to locate.

The bottom line: Cox found limits to the diversity at Regent, but they were limits that left him thinking about Harvard culture. In terms of debates on critically important topics, which school was more diverse?

I thought of that classic Cox essay a computer click or two into a must-read new essay at The Atlantic that ran with this double-decker headline:

The Geography of Partisan Prejudice

A guide to the most—and least—politically open-minded counties in America

So where does one find diversity that matters, people who are trying to be tolerant of their neighbors who represent different cultures and belief systems? You wouldn’t know that by reading that headline.

So let’s jump-start this a bit with the headline atop the Rod “Benedict Option” Dreher take on this piece, which has been updated several times (including his detailed reaction to a criticism from one of the authors). That headline: “Least Tolerant: Educated White Liberals.”

Where is Dreher coming from? Here is a key passage in the interactive Atlantic piece:
