I'll define a 'true Christian' for you. It is someone who practices what Jesus preached. That is, absolute pacifism, under all circumstances. If someone hits you, turn the other cheek. If someone rapes your mother, turn the other cheek. And so on. He preached that violence against others is wrong, no matter what the circumstances are. Thus, there are really very few true Christians around, because most people believe in self defense and the like. There are many who talk the talk, but few who walk the walk.
