the article linked in the OP differentiates between atheistic and secular states, correct?
North Korea didn't become North Korea because they decided to be atheists. North Korea (the dictatorship) decided that they should worship the dictator more than god. So the state atheism has no bearing on who they are as a country, its part of the symptom of who they are under a dictator not the cause. Spurious relationship. Not weak. painfully obvious to most idiots but yourself. Its even more obvious when you consider other data such as nations that are made up of atheist people (hard data exists....not weak) are generally happy and have a higher quality of life than even us. You can lamely call it weak without any rationale, or you can do some research on the rate of belief in god in scandanavia and their quality of life. Clearly, state atheism isn't what causes a north Korean situation....it is a result. A god-like dictator existed first....then religion had to go because it was in conflict with dictator-worship. Atheism itself has nothing to do with Korea's status.
Google "spurious" zolace.
Actually,you have proved nothing. The states noted in the OP link were atheistic states.
Now, do you have a link describing the nations you refer to as atheistic? Not secular, but atheistic? Having alot of atheists in a secular state is not the same as having an atheistic state.
