How to tell if someone is an atheist

Blogmeister wonders how to tell an atheist from, well, a human being:

A rally will be taking place at noon in the city of Milford, Connecticut today in support of the phrase "under God" in the Pledge of Allegiance. Members of the Knights of Columbus plan to fight the federal court ruling in California that said the phrase "under God" is unconstitutional, and today's rally is to bring awareness and drum up support.

Atheists will be right there counterprotesting.

Dennis Himes, state director of American Atheists, said his group would be there to counter-rally, because the addition of the phrase to the pledge was "directly aimed at atheists in the first place and is trying to say that we’re not true Americans."

He seems a little paranoid! After all, I would't know an atheist to look at him unless he went around with a sign hung around his neck proclaiming his beliefs (or lack of them).

A professional atheist does have a sign around his neck or in his hand, as he stands out in the cold protesting a Santa Clause display on goverenment property. Or his hand is full of legal papers, as he happily brings lawsuit after lawsuit. If you talk to him, within 5 minutes he will reveal how Bush and the Christian Right want to destroy his civil liberties. The species is eaasily recognizable.

I'm not talking about agnostics, skeptics, or non-believers. But professional atheists are a breed apart.
