With atheism becoming an increasingly growing phenomenon not only within the U.S. but the UK, many of us would take exception to a commandment prohibiting blasephemy or the taking of the Lords name in vain. This is not only undemocratic but runs contrary to free speech, more along the line of prohibiting criticism of a President or any other public official.
The same with idolatry, and the establishing of one God, monotheism, or one supreme God, henotheism, also runs contrary to the American constitutional guarantees of freedom of conscious and against an establishment of religion. People are free to worship many gods, one, or none at all.
Adultery, if that is what is implied within sexual immorality is a broken promise between consenting adults, and has nothing to do with a government. It can and often does result in a broken relationship, affecting the children if the marriage breaks up as a result of it, but it hardly merits as that of a harmful felony.
Prohibitions against murder and theft existed millennia before the time of Noah, or even the Israelite story of Moses coming down from mount Sinai, relative to humanity, these are obviously wrong, universally.
