Are Christians really divided primarily by our views of sex?

Interesting exchange last week between Rod Dreher and Andrew Sullivan, two fine bloggers often at odds with both major parties and sometimes with each other, too.

First Dreher posited that the major difference between traditional and progressive American Christians basically comes down to one thing: sex. That is, traditional vs. progressive beliefs about it. When it comes to the public square, argues Dreher—as distinct from various philosophical and theological debates with less immediate public relevance—the sex-related stuff pretty much says it all.

Sullivan countered that the big difference is how much, not what, we think about (other people's) sex. "The trads see sex as the critical issue," he said, "and we moderns see a whole host of other issues."
