This is a great point. I don't see why somebody should be able to steal my motorcycle- the object of my affection- and me being helpless. What's next, somebody kidnaps my girlfriend and I have to watch them take her away?

This is literally the case in many places that have laws about the "proportionality" of self defense. If the guy is much bigger/stronger than you, but unarmed, if you use a knife or gun to stop him you could go to jail. But as the saying goes, better judged by 12 than carried by 6.

You own your girlfriend?

Do you really think that's what the GP was implying?

I was just noting the Freudian slip.
