The passage on turning the other cheek is the most misused one ever in any discussion of self defense. As an expert in this area, I can tell you that a slap on the cheek (Christ is not talking about a punch) is an insult in any culture, but is not a damaging blow (unless you are a Sumo wrestler). If a bad guy comes in my house, I'm not going to slap him, I'm going to attack his vital points.

Word Pictures on Matt. 5:39--"
One thing certainly is meant by Jesus and that is that personal revenge is taken out of our hands, and that applies to "lynch-law." Aggressive or offensive war by nations is also condemned, but not necessarily defensive war or defence against robbery and murder. Professional pacifism may be mere cowardice."
But hey, at least you've finally found a verse to talk about besides "Love your enemy."
Sorry, you have no credibility left with me since you compared me to a violent criminal, Al Capone. You are supposedly the non-violent one, yet you are committing verbal violence with this comparison. How hypocritical. Your insult has shown that you have no love for me. You'd do fine loving a vicious criminal like Al Capone (who is not my enemy, since I never knew him; therefore I don't have to love him).
