"Because I believe there is no scientific evidence to support the existence of an invisible man in the sky" is just a different, arguably more intellectual (and definitely more condescending), way of saying "because I have no reason to."viranimus said:However, the notion of atheists not believing in an ideology is patently false. It is not false in definition alone, but it becomes false in practical application. When your lack of belief transcends the point of simply saying no when faced with a theist and the individual feels compelled to discuss and defend that ideology it is no longer being devoid of belief, but it in itself becomes a belief.
Non theist:
A: I believe in God
B: Ok, I dont.
A: Why not?
B: I dunno, Just dont.
Atheist:
A: I believe in God
B: I dont
A: Why not?
B: Because I believe there is no scientific evidence to support the existence of an invisible man in the sky
You basically cannot have a lack of belief when you believe something to support your lack of belief. Richard Dawkins is a Good example of this as he is an individual who believes there is no God and feels compelled to try to prove a negative and he does so by creating his own system of beliefs to justify his ideology.
So when people come onto a message board to "preach" to others about the evils of religion, they are in fact expressing a system of belief that they have, because they believe it to be true, but there is no way to prove it to be true.
One could perhaps argue that atheists have an ideology based on the virtues of science and critical thinking, but on the other hand you'll find plenty of theists in that same camp (except when their religion is involved) and atheists that believe in other sorts of superstition.
Finally, belief in "the evils of religion" and atheism are wildly different things. If the religions in question are exclusively theistic ones, then we've got us a case of antitheism [http://en.wikipedia.org/wiki/Antitheism], rather than atheism.
