Who is Poe ... I really don't know?

There's a saying called Poe's Law which maintains that it is impossible to distinguish someone who is pretending to be a member of a religion in order to make members of that religion seem stupid or vile, and an actual member of the religion who is actually stupid and/or vile; unless they give themselves away somehow. A person who does that is called a Poe, and it usually is considered to be an atheist pretending to be religious. It's trollish behavior.
