You're all wrong about this (but that doesn't surprise me).

A "fundamentalist" is merely someone who focuses on the fundamentals (the core doctrines) of his "faith" (in quotes to include Skerlnik's secular examples). You are confusing fundamentalists with radicals and extremists.

A panda walks into a cafe. He orders a sandwich, eats it, then draws a gun and fires two shots in the air.

"Why?" asks the confused waiter, as the panda makes toward the exit. The panda produces a badly punctuated wildlife manual and tosses it over his shoulder.

"I'm a panda," he says at the door. "Look it up."

The waiter turns to the relevant entry and, sure enough, finds an explanation.

"Panda. Large black-and-white bear-like mammal, native to China. Eats, shoots and leaves."
