Your challenge: With a PoD of 1918, Have the peoples of western (Europe and North America) countries noticeably more religiously observant than the people OT 21st century. By "more religiously observant" I don't mean people under a theocracy, but observance as much greater than 'something grandma does on Sundays'. i.e. people don't live their lives around religion, but at the same time, your typical bloke takes it seriously.
