I do believe the modern (us) conservative evangelical "back to basics" movement started in the 30s/40s as a response to rampant alcoholism from the great depression. Church of christ and similar denominations. They take a (claimed) "hyper" literal approach over a few key issues, like alcohol, sex, drugs, taxes, tithing, homosexuality.. Recent history was the 90s abstinence movement.. And in the last 7 or so years these have been the churches taking the brunt of the exodus and have been largely deflated, with churches across the nation dying due to lack of new young people.

I would wager good money that most modern conservative US Christian families have a male alcoholic relative not too far removed.

The alcoholics and Christians go together.
