I guess I'm going to disagree with the notion that I don't understand natural law. I am, however, interpreting it differently from the way a number of traditions do, especially the Christian one.

That's because I reject any supernatural interpretation of natural law.

To pick just one example from your criticism, when I say that "there is room" for different opinions, I am referring to things that are not and cannot be specified by natural law. The latter is necessarily generic, addressing the human condition only in the broadest terms. Which leaves room for reasonable disagreement on everything else.
