I disagree. Atheism isn't a belief. It is the lack of that. It is saying "I don't believe in a god". No claims are made and thus no explanation is required.
To me, you sound pretty arrogant. It is evident your only wish with this post was to express how much of a true atheist you are and how you didn't believe before it was cool. Give me a break.
except im not an atheist. im a polytheist, i have many gods, but they dont run my life.
atheism has become a trendy position for those hipsters who wish to sound intellectual, or prove their independant bonafides, but atheism without a rational reason is still just blind faith, whether that faith is in preists rabbis ministers and mullahs, or noam chomsky, richard dawkins or vladimir lenin.
you seem to forget that the soviet union was also "Officially Atheist" and party members would go to great lengths to prove their lack of interest in religion, regardless of whether they actually disbelieved or not.
it's easy to put on the trappings of belief/disbelief, but without a logical, intellectually sound, and moral reason for either, both are simply a fashion show for others, which is what many "atheists" do, they put their atheism up front and center, as their glorious cruaders' tabbard and dare anyone to challenge them, much in the way many "religious" persons do with their faiths
your faith or lack thereof should be personal, internal, and private, not a sandwich board that challenges anyone from the other side to a fight.
