That's a reasonably "major" concept in a country whose main principle is individual freedom, or is supposed to be, at least I think so.
I see this as reflective of MissouriConservative's Christianity, which is a fine thing, but it's also getting to be law that respects an establishment of religion. I like better the kind that allow the free exercise of such, not the kind that mandate it.
The same way I square the laws on speed limits, drug usage, drunk driving laws, pornography laws, age limit laws
Those laws specifically protect citizens from harm, blue laws don't, the analogy, I think is not valid.
My analytical side tells me that freedom should reign supreme, but my practical side has to acommodate much that that I've witnessed, which often includes a little more of a cesspool environment than I'm willing to accept.
FWIW, I think we've strayed way too far from real freedom, but I suspect that's a topic for another thread. :-)
