The PC culture has made it harder to identify as a "believer". That's fine. Those folks were never really that into it to begin with. A time is coming where a person will really have to count the costs. And I am not talking some idiots who wouldn't bake a cake or some other self inflicted victim hood.

That's always been part of the equation. For some of the Religious categories in the survey 80% married within their own religion. If your group is only 10% of the population, there can be a significant interplay between romance and belief.
Historically the stakes were often much higher, including a cord of dry wood for those who did not toe the line.
