Of course it wouldn’t appear that protestant churches were affected in the same way that the Catholic church has been. That’s because protestant churches have split endlessly, so there’s no formalized doctrine between them.
Some argue that Catholic annulments have skyrocketed since VII, but that there’s no corresponding divorce rate among protestants. Well, how can there be, since in many protestant churches today there’s no sin attached to living together? If a cohabitating couple splits, no unfavorable statistic can be attached.
If you belong to a religion where anything goes and nothing is “wrong”, then it’s difficult to ascertain whether your members are practicing or not and “problems” become transparent.
