The first step was legalizing premarital sex thus inventing the "between two consenting adults" argument.
The second step was either not having statutory rape laws apply or just not enforcing them when both parties are underage thus normalizing minors having sex.
But even here where almost every other post is about seeing a pedophile under ever rock you still can't see these major advances made against our children's innocence.
Nope. Thank God I found my man young and we got married. I know my daughters. Married happily. The thing with prohibition, drugs, sex, rock 'n roll.. whatever.. these are personal morality issues. If we have laws against them, obviously those laws should be followed (or changed). I personally think people are stupid for doing drugs, drinking to excess, having sex willy nilly, etc. Am I willing to violate people over it? That's what you're asking us to want to do. We live in a fallen world. You would bring greater change showing the light and love of Jesus rather than bashing them over the head with legalism.
The way I see it almost everyone will obey orders when there is an immediate consequence backing it up, it's harder to sell people on promises of a good life though, especially to those with a pessimistic outlook on life.
