But, of course, every law has a moral underpinning. But I ceratinly understand your unwillingness to discuss that.
Not at all. Every law does indeed have it's basis in morality, or at least the morality of those who wrote the law. But once it is codified into law, it's application is done amorally. Moreover, the question becomes wheather society's morality should conform with the law, or wheather the law should conform with society's morality, and is that relationship consistent?
Is smoking marijuana immoral because it's illegal, or is it illegal because it's immoral?
Is abortion legal because it's moral, or is it moral because it's legal?
Are the two always related?
