I think of it as Germany’s extremes in one state, if you will...the crazy intellectuals ruminating about the death of God, alongside tradesmen and farmers who measure the height of their lawn with a micrometer and whose daily routine could be used to check a watch for accuracy.
Wisconsin has full churches. And lots of them. Lutherans and Catholics fill the churches. They are down over the past 50 years. Certainly they are not what they used to be. But they have higher attendance than most states. Drive through Wisconsin and count the steeples. I think you will be impressed.
