America is a nation in the Christian West, a place the world once called "Christendom." Freedom and liberty in America are defined by Christianity. No matter how disordered our society is at present, we are still not an anarchy. You cannot drive on the left side of the road if you want. Every society has rules, and Christianity informs the rules of our society.
Two thousand years of Christian thinking cannot be decoupled from secular America. The very word "secular" is religious. It means that some activities are less ordered by the demands of Biblical holiness and righteousness than others. The word does not mean that some activities are holy and others are not. Forces who are interested in reducing the status of Christianity from religion to superstition have changed the definition of the word secular, as they have changed the meaning of so many other words and concepts.
The word "gay" comes to mind, as does the meaning of the rainbow, as do the words "Freedom of Choice." But that is a topic for another time.
The safest society for atheists is a Christian society. I've noticed that atheists and pagans aren't lining up to emigrate to other parts of the world.
Why is it safe here?
Christianity teaches us to love our enemies. We don't use terror as a weapon. Christians will kill if they must, but they won't murder. And that is an important difference.
If atheists and liberals are really interested in confronting bullies, they'll put outspoken Christians in public office.
