As long as all religions can practice is the key. Their infusion is vital to our survival.History says differently.
The Papal States and the Caliphate are two centuries -long counterpoints to that assertion.
The United States is what I would term a "secularized Christian nation"...
With its collective law and morality and traditions very deeply rooted in Christianity...
But with very liberal and generous accommodation for other belief systems in peaceful coexistence within the Republic.
The way it should be.
