A checklist
This is good news I think:
Yahoo! News - Supreme Court to Hear Commandments Case
It seems to me that if you can take a science fiction writer's teachings and make a religion out of it, as people have done with L. Ron Hubbard, and some are attepting to do with George Lucas then all secular writings should be banned as well.
Every writing comes from a worldview. All worldviews either include some form of God, or exclude some form of God. It is impossible to discuss moral issues and issues of justice without having a worldview.
I don't think that there is much of America left that values the 10 commandments. Adultry is not a crime. Coveting is a core American value. It is difficult to honor the father and mother who are absent, or unknown. We are expected to lie nearly all of the time. Most every business is open on the sabbath. It is considered intolorant if you don't accept that there are other Gods who are equally worshipable. I would guess that the vast majority of the time that the Lord's name is used in this country, it is being used in place of a swear word.
America seems to look at the 10 commandments as a checklist of rebelous actions to take.
Putting up a monument does not a religion establish.
Now by "Most every business is open on the sabbath" do you mean Saturday? ;-)
