You're only really a liberal democracy if the ruling elite can coerce private actors to take the repressive actions instead of doing it officially.

The topping on that cake is that the US is that the US is the most religious developed country in the world, more so than countries like Poland.
Which is why Supreme Court appointments get so heated here.
