In High School I would constantly visit The CIA World Fact Book online and read about a different country per day. Sometimes more. I'd read about the Country's imports/exports, partners in trade, past and present GDP, National language, Literacy by gender, birthrate, mortality rate, average age by gender, percentage of population by age group, military stats, Culture, ect. My favorite sections to read had to do with economic standing. It is just a wealth of knowledge and a great way to understand what makes the world turn or at least what makes or breaks a country.

A key thing to remember in order to link the subject to the intro is that in addition to all of the stats that the CIAWFB includes, It also includes the national religion(s) and the percentage of how they are allocated throughout the population. So as I learned and learned I'd often imagine what a state of atheism would/could be like. I'm pretty sure I'm not the only one who has contemplated what our countries would be like if our people, if our leaders, if our cultures were free of religion.

Although I neglected to come up with a name for this theoretical country, my imagination for the details had no limit. I'll try to keep this brief. I'd imagine that the Atheist community had grown to such a size in population and wealth, that it could purchase land from another country or even perhaps claim an island that had no territorial claim. Maybe somewhere in the Pacific? I don't know.. Why not? Either way it would be a country for Atheists BY Atheists. Sounds cool right? Yeah... I've had a lot of issues making this make any sense ethically.
On the bright side of the fantasy, I'd imagine the Atheist state advancing rapidly in the fields of Physics, Technology and the Medical field including psychology. The culture would allow even ordinary citizens to value and be proficient at advanced mathematics and at least some branch of science. Moral culture would not be contingent on the psychologically child-level of the punishment&Reward system. so it would be overall better. I had imagined Esperanto would be the national language. A particularly simple language to learn. The name "Esperanto" in Esperanto actually means "the hopeful one" a concept that is ironically not atheist, but at the same time it is a constructed language that is young enough to not have so many religious sayings tied to it.. which is why I chose that. Other than that I worked out a myriad of other details, but let's move on.

Being from the U.S. I have a bias towards of the idea of freedom, but then how can religion really be kept OUT? Should humanities education include religion the same way it includes other mythology? would there have to be a building restriction to prevent churches? what about censorship of television and the internet? Travel restrictions? How can such a state have freedoms with all those restrictions? Furthermore, What countries would trade with The atheist state? Would the Atheist State ever NOT be in danger from the threat of religiously driven terrorists? Holy warriors? Vatican assassins? lol It's unclear to me at this time.

I don't claim total knowledge. But knowing what I know about international politics & how countries operate, I've concluded that in these times... The Atheist State can only exist in dreams. I'd love to hear your thoughts and Ideas.
