"Arkansas is one of half a dozen states that still exclude non-believers from public office. Article 19 Section 1 of the 1874 Arkansas Constitution states that "No person who denies the being of a God shall hold any office in the civil departments of this State, nor be competent to testify as a witness in any court."If you don't believe in God, you are legally barred from public office, and you're not even legally allowed to testify in court. I'm literally appalled that such a law exists, despite the fact that such laws were deemed unconstitutional by the American Supreme Court in the 1960s.
So next time you hear a Christian spouting their persecution complex, remind them that at least they're not legally second-class citizens in half a dozen states.
EDIT: Seems this has also been covered by P.Z; might want to head over there for a more comprehensice writeup.
