Unenforceable laws can have a purpose. Take the anti-sodomy laws, for example. As far as I know, police have never knocked down doors trying to catch people in the act. The purpose of the law was to serve as a basis for other related laws, such as laws prohibiting gay "marriage," prohibiting the promotion of homosexuality in public, prohibiting the promotion of homosexuality in public schools, prohibiting the adoption of children by homosexuals, etc.
As we have seen, the floodgates opened as soon as the Supreme Court struck down anti-sodomy laws.
Excellent insight. The clear relationship between law and morality is what is being broken. It’s the secularization of law and the promotion of the state as the ultimate authority.
Note bene that liberals demand that the state enforce their beliefs. They are not non-religious, they just hate Christianity and God.
