I see the "showdown" as not between conservative and liberal Christians nor as between conservative Christians and a coalition of every other citizen in this country.
What I see is the possibility of the extreme conservative Republican congress persons (are there any radical religious Republican women elected?) driven by the radical religious horses that got them there actually going so far as to legislate something that seriously alters how life is lived in this country.
I see these foolish people - remaining however a minority and not representative of traditional conservative Christians - triggering a showdown between right/left and liberal/conservative that explodes in an uncontrollable way that forces the rest to choose sides.
It's one thing to enact laws the keep taverns 200 feet from churches. It's something else to enact laws that seriously alter our national habitual understanding of - for example - our Bill of Rights.
If that happens, these radicals who thought changing the laws was all that was needed will have no clue as to why rioters don't "play fair" just because "it's the law now" and quietly go to jail themselves instead of striking back.
If laws were enacted, the first time a jury found a Chrstian Taliban executioner of an accused gay, liberal or abortionist not-guilty I think the Pharisees would have more than they could handle.
Would you just sit around and moan if every week a van came down your street and you watched as your gay neighbors, your neighbor who had a private abortion, or liberal speaker-outers were loaded up and hauled off?
Not for long ...
That's the naivete behind the assumption that enacting laws enacts a specific morality.
