The problem at its core is that sexual sin has its fruits. Sex education and contraceptives are poor solutions to the problems created in a society that venerates sexual sin. Sin is a spiritual issue, and it will always require a spiritual solution. The problem is that the state does not have the means to fight spiritual battles. When a society suffers because of rampant sin there is nothing that the state can do to solve that spiritual problem. That is why a purely secular society will never work. Sin always bares fruit. The solutions that these liberal statist types propose are essentially putting a band-aid on a lethal wound. It just doesn't work. The solution is a society that repents and turns back to God forsaking its sexual sin.
