Thank you so much for saying that! You seem to be the first person who truly understands what agnostics are about! I am not part of an organization or group of any kind. Its truly not a decision to be agnostic, but rather the lack of a decision to put absolute faith in any one belief system due to the lack of knowledge of God. I am agnostic but am always in search
of absolute truth if it truly exists. But back to the original question, NO. Agnostic have no emblem or symbol. That would imply loyalty or dedication to a specific area or group. As an agnostic, I claim no religion or specific belief system outside of the knowledge my own studies have yielded.
