I'm not saying it's not wrong, but as it is religious, should an aetheist have to conform to it?
We don't follow the Ten Commandments as laws. Many of the ancient laws that we have adopted from society come from Hammurabi's code and from even before that.
Feudal Japan had thousands of laws. Many still survive. Communist China has thousands of laws, many or most have a commonality with American laws and even biblical laws. They're not related, but stemmed from the desire for order.
Order isn't a religious concept. It's secular.
