The Church of Critical Thinking.

The Church of Critical Thinking is not a religious organization, and it does not acknowledge the existence of any deities. The Church of Critical Thinking believes that separation of church and state is a very good idea, but is frustrated that the separation is becoming increasingly blurred.

The goal of the Church of Critical Thinking is to teach people to use Critical Thinking skills to analyze what they're being told, to be skeptic where appropriate, and to reject ideas that they may already hold as true if they don't hold up when examined critically.
