Worst atheistic argument?

[theVOID]

Atheism is not a worldview, is is a rejection of a claim, the claim that God exists.

So, it's "Metaphysic" is that there is only a natural reality, it's "Epistemology" is the scientific method tempered by Logic and reason, and it's "Ethic" is the majority in a society rules.

It's got the three major components of a worldview, therefore it is a worldview.

Get it now?

1)
Atheism = only naturalism/materialism?
No, because you can still be an atheist and believe in the supernatural, such is the way of the Buddha.

2)
An atheist must use science as it's Epistemology?
No, You can have non-scientific atheists, such as Buddhists again, or Raelians, or the pre-Socratic philosophers many of whom rejected the idea of a God before there was a scientific method.

3)
An atheist must believe in subjective morality?
No, You could believe in absolute morals whilst being an atheist if you believed in some cosmic or supernatural law excluding a god, Taoism is a good example.

You failed on every account, it's because you are arguing against the very established definition of the word atheist, from the latin A(Without) Theos(belief in god(s)). Theist likewise literally means "belief in God" but i bet you wouldn't argue Theism is a belief system or a world view, you would be an absolute idiot to do so, as you have been arguing that atheism is. Theism is a single statement, Christianity is a belief system.
