In situations of de facto diversity, attempts to impose a single way of life on an entire population is a formula for dictatorship. - Francis Fukuyama

[T]here are defects and gaps in a liberal society that are constantly being filled by other longings and... structures... that sometimes end up undermining that liberal project.

A right exists in theory... [A]ll human beings have the same set of rights, but rights need to be enforced by the state. It needs to rely on the coercive power of the state... its army, its police force, to actually make those rights something real that citizens can enjoy, and the enforcement power is not universal. ...[W]e wouldn't want to live in a world in which every liberal state wanted to enforce liberal rights in every other state in the world.

[T]herefore tolerance of diversity, of people that don't believe the same thing that you do, has always been at the core of this pragmatic project to enable diverse populations to live with one another.
