Yeah but in a theocracy, you're gonna end up with a bunch of half-hearted followers, so you're gonna have the same statistics as if you had freedom of religion, but people would secretly hide their religion.
And my State has a better approach:
"The World is evil
The State will protect the citizens"
Create a sense of safety, so instead of fearing the State, they'll fear everyone but the State.
Are you still a dictatorship?
No don't pay attention to what it says. Because I don't consider it part of role play
