The wonderful message of atheism is..........there IS NO message.
Atheism is not a positive assertion, it is the antithesis of a positive assertion.
If I happen to not collect stamps, I am NOT sending out to the world a *message* of ----- "I am a non-collector of stamps, join me."
And since atheism HAS NO message to deliver, you can rest assured that --
*no atheists will come knocking on your doors trying to get you to join the atheists,
*atheists will not be demanding of the government that their non-belief be granted tax free status,
*atheists will not be lobbying state and federal governments and the public schools that a shaman/preacher/whatever from the atheists be allowed to chant some psychic imprecation to otherworldly powers before a ball game or session of Congress can commence.
*atheists will not be demanding that some arbitrary, predetermined set of ten "rules" that they want all other citizens to follow be mounted at the entrances to the courthouses of the nation.
And on, and and on, and on.
