Once again, some hick town has a few redneck ignoramuses thinking civic law is defined by a few Old Testament commandments. It isn’t.
Yes. It’s good to remind people of God’s laws governing our behavior.
No. It violates separation of church and state, and is offensive to non-Christians.
God’s laws say I can’t mow my lawn on Sunday, can’t have a statue of Buddha in my house (we do, actually), and can’t appreciate an attractive starlet on TV. Why should a town praise a bunch of bad laws they won’t ever enforce?
