The Fundamental Problem with All Religion

The common denominator to accepting literally any type of religious doctrine is the belief that something is inherently wrong with you. One must foundation themselves on this: "I am a bad person, and I need something from outside me to save me from myself." 

This is a relatively easy sell, because everyone is capable of committing evil, and everyone has at one point in time made mistakes and wrong decisions. The reason why this is a dangerous first step to take in the critical thinking process is because it ultimately removes the individual from being personally responsible for themselves. One becomes a victim to forces outside his/her control as opposed to their own doing.
