It's rather naive to call an atheist not open-minded. Are we not infact entitled to the freedom to search and gather knowledge and come to our own determined thoughts? That's the fine line between non-religious people and religious followers. Non-religious people, for the most part, were apart of a religion prior to deciding that it was not for them or that the religion itself was fraudulent. Religious people grew up into that "lifestyle" so to speak, so they know nothing else, and are subjected to that type of "brainwashing" hence the contradictions that are included in the Bible to farther more suppress your mind from thinking otherwise. "Thou shall not believe in another God" etc. Next time you try to throw down your rhetoric, actually think it through before you say something heinous again without realizing the rammifications of your actions.
It is infact intellectually known that atheists are open-minded people because they WANT to believe that there is a God or higher being but they/ are people of reason not false hope. Who wouldn't want to believe that there is heaven where you are fed fresh grapes right off the vines? Exaggeration but etc. That is the misconception that most religious zealots have. After a thorough analysis by these open-minded atheists, they have further more come to an absolute conclusion based on "proof" that the existence of a religion does not infact exist, so further more divulging your life, time, and resources to that cause, seems rather unfathomable. Resulting in there minds becoming closed because they have systematically gone through trial and error with both the contortive and fallacious teachings of each religion.
WORD UP. Just like someone who has converted to another religion is usually a better follower then someone just born into there religion. Being an Athiest is like converting to non-religion lifestyle.
