The US state is officially atheist, yet somehow requires people to be non-atheist to become a govt official. There has been only one avowed atheist in Congress in recent memory, and several more who felt necessary to lie about being non-atheist.

Several US states are in fact officially theist and requires the same to become a govt official (despite apparently violating the US Constitution.)
