I absolutely agree that you are trying to apply logic where logic doesn't live. Hahaha. I'm actually surprised they got civilly married and didn't just hold some ceremony themselves in the forest, but my guess would be because of the optics, particularly for Chad's children, who would absolutely condemn sex before marriage. But you're right, their beliefs are ludicrous and don't make logical sense. I mean, killing people would be right out, too, but apparently they've gotten around that idea with some serious mental gymnastics.
Ha. I think Chad's children would also condemn sexy dancing videos before marriage too. And also while still being married to someone else. Their mother.
