No, but I just have doubts about the entire premise of natural law. Is murder bad because there is something inherently, naturally bad about it or is it just because most of us don't like it? I don't see how there can be anything more to it than a general consensus and that breaks down the farther from things like murder that you go. Alcohol, gambling, porn, same-sex marriage etc. To approach these issues as if there is some kind of inherent naturally-occurring objective morality rating to be found in them doesn't make sense to me (I know I'm probably missing the point, out of my depth...)Just because loonies are invoking it doesn't make it de facto a bad thing.
Devils quoting scripture and all that.
