The scariest thing I hear time and time again from Christians is the following.
"I don't trust people who don't believe in god because they have no moral compass."
They say this in such a matter of fact way. Most people have a good understanding of right and wrong without a rule book. For many that "moral compass" is intrinsic, even instinctual. It is an evolved part of humanity that helps us operate within a society. The Christian's are saying it is a core piece of humanity that they lack and since they model their perception of others after themselves they cannot fathom that concept. They are broken humans who without a ruler/leader would be dangerously unpredictable and violent as they have no system to make good choices. This is why those same people prefer a king.
