The Freedom from Religion foundation is an organization dedicated to "Protecting the constitutional principle of the separation of state and church".

As a Buddhist, my spiritual worldview makes answering the question "is there a God?" a little more complex than merely saying "yes" or "no", so I wouldn't necessarily qualify myself as a "nontheist". Still, I can say without reservation that whatever is out there is most definitely not what a fundamentalist Christian, Muslim, or Jew would say is out there. If you really think God (or Allah, or Jaweh, or whatever) is just a really tall white/arabic/semitic guy with a beard and a bad attitude, please wear this sign so I know you're not worth talking to.

I'm very comfortable with an organization that makes sure these kinds of people are unable to shove their beliefs down the throats of my or anyone else's kids. So give them a check-out, if nothing else to give Pat Robertson et. al. a little poke in the eye.
