In more malevolent tyrannies of modern secular societies, the state uses its monopoly of coercion to bulldoze the slightest degree of liberty of its citizens and grind humanity's collective face into the mud. It is ironic no, laughable when secularists express fear that a Christian society will somehow undermine liberty and freedom. By far the most tyrannical, murderous political regimes in history occurred in the twentieth century, and all of them were secular. There is a good explanation for this. A secular society imposes no barriers to state power.
Political leaders are accountable to no one.
They own a monopoly on firing squads, electric chairs, nuclear weapons, and, in some cases, guns. Therefore, they can torture and kill people if they want to. By contrast, a Christian society contains built-in barriers to tyranny. The most notable one is the fear of God. For this reason, an honest atheist and there is no genuinely honest atheist would prefer a Christian society to an atheistic society.
