Eric Zorn writes in Breaking Views (no permalinks):
Those tempted to side with the religious activists in the controversy in Alabama about the display of the 10 Commandments in the state’s judicial building should remember this: Only three of the commandments reflect actual laws: Don’t steal, murder or bear false witness.
Another four–honor your folks, stay faithful to your spouse, don’t be covetous and refrain from profanity–are simply good ideas, not generally matters of law.
The remaining three–keep the Sabbath holy, make no graven images and have no other God before the Judeo-Christian God–are fully religious prescriptions.
Making graven images may or may not be a good idea, but unless I misread my Constitution, we’re all free to do so and risk the consequences. Any sign on government property that implies otherwise is poisonously wrong.
Again, ’nuff said.
