**Edit: A more elaborate description of this stamp: "Fundie" is what some people call Christians who believe that everything in the Bible is true, that the world was created by God in 6 literal days, that Jesus Christ was born of a virgin and that He will return at the end of the age, etc. They mean it as an insult to put us down. A lot of Christians take it that way, too, and try to distance themselves from that word. But I think it's something each of us should strive to be. The message of this stamp is that being called a "fundie" isn't an insult; it's honorable.
As in extremist.
As in suicide bombers are a form.
