Atheism's Definition - Stanford Encyclopedia of Philosophy

[Ben Davis]

Actually they are mutually exclusive, unless you are confusing atheism with irreligiosity.

Wrong. Simon's right, you've had this explained to you many times:

Theism/Atheism describes what you claim to believe
Gnosticism/Agnosticism describes what you claim to know

Unless of course, you're claim is that knowledge & belief are identical in which case I'm unsure but don't believe you.

I mean, you can call yourself whatever you like, but if all you do is disbelieve, to the real world you're just an agnostic.

You can call yourself whatever you like but if all you have are 4 legs & a flat surface, to the real world you're just wooden.
