Yet consciences can be educated and influenced. Christians, whose liberty of conscience is just as sacred as that of non-Christians, should be free to influence others toward the Christian worldview. All societies have a standard. Christians can raise their standard and use all legitimate educational and political means to promote that standard for their country. Non-Christians are free to do the same.
Pluralism is a different concept altogether.
The basis for modern pluralism is moral relativism. Those who advocate pluralism usually don't believe in absolute truth. They say that all views receive equal treatment, but there is a concerted effort to censor any view that promotes absolutes. The assumption is that morality cannot be legislated. Every law is a statement by the political community declaring certain actions to be wrong and others to be right.
