The answer lies in its liberal message: do not criticize or punish immoral conduct unless you are perfect yourself. Liberals cite this passage to oppose the death penalty, a misuse that has been criticized. But one need not be perfect before he can recognize wrongdoing in himself. The Mosaic laws clearly state death as a punishment for sin. So the argument that an individual must be perfect is not relevant. The God-ordained government has the responsibility for punishment. Civilized society may not depend on stoning to deter immoral crimes, but it does depend on retribution enforced by people who are themselves sinners.Also, the Gospels as presently extant are not sufficiently pro-free markets.
If this is a hoax, I'm deeply impressed. If not, I expect them to sue TEC for property.
