Again, X, this is not in regards to the American historical tradition, but whether or not a Christian, qua Christian, is acting wisely in promoting laws based on his or her beliefs.
You are entirely missing the point being made, per usual.
The question is, as religious beliefs are founded on faith, and faith is founded on free will, if we might consider ourselves wise to make laws based on God's dictates, particularly when you consider that Christ himself said "give unto Caesar that which is Caesars."
Once religious faith laws are taking into the political spectrum, not only do they lose the article of faith that made them favorable to God, but they also become enmeshed in the single most crooked profession known to man, even including that of the lawyer. And, then the greater question becomes begged when you consider that, to God, all sins are created equal. Thus, to lie is as bad as to murder...so we must, if making laws solely from religious views, they must be treated equally, and we must receive prison or death for telling lies.
I am not saying that Christians should keep their religious views to themselves from a purely secularist point of view, but rather of one that would protect a historical tradition of personal faith and understanding.
