Atheism is a rejection of the assertion, "there is a god," and it is NOT necessarily the belief that there isn't a god.
There is a pervasive misconception about atheists that goes as such: "Atheists believe there isn't a god. Therefore, they have just as much faith as any religious person." While that argument is valid, it's unsound; that is, the conclusion is ba<x>sed on the faulty assumption that atheists believe there isn't a god; while that certainly is the case for some (probably few, actually) atheists, it isn't the case for all atheists. I don't believe there's a god because I haven't been presented with reasonable, acceptable evidence for his existence, and so it would be unwarranted for me to assume that he doesn't exist. I reject the assertion, "there is a god," but, in so doing, I am NOT claiming that the assertion is false; I am essentially saying that I can't be sure that the assertion is true, and so I won't accept it as truth, and I can't justifiably claim that it's false. After all, absence of evidence is indeed not evidence of absence. Ya dig?
