Not the OP, but the concept "sin" is nowhere nearly as physical as the shape of the Earth. I would even argue that for non-religious people, the concept is entirely irrelevant, with some exceptions, and religious people shouldn't try to legislate anti-sin policies into law. [Exceptions:] If you live in a heavily Jewish neighbourhood and sell sandwiches, it is a good idea to have kosher ones as well, even though you personally don't care about mixing of cheese and ham.
