I know people from Leavittsburg and they don't seem to be into cousin-fucking as far as I can tell. However, arson is apparently a typical teenage courtship ritual. I imagine they have to do it because the Amish can't stop themselves from raising barns and someone has to keep them in check.
Well really if the barn population goes unchecked pretty soon they will consume all the straw and the landscape will become a strawless hellscape and they will all end up with no straw to consume.
