Seems to me that <i>sport</i> and <i>killing</i> are two different purposes. And I'll add a third: threatening/show of force.
Touché. Not sure that's comparable though. Many factors beyond your control dictate the use of protective moto gear at the track. An unexpected loss of traction or someone else wadding into you, etc, are reasonable risks you accept there. Pulling the trigger of a gun by mistake would seem to me like randomly whacking the throttle wide open in mid corner, spinning the rear wheel. A rookie mistake. If I didn't <i>know</i> I was not going to do that, I wouldn't be on the track.
But I dunno, stealing stuff outdoors is one thing, but if a stranger is in my house, the m-f'er will probably be looking down the barrel of my (for now imaginary) gun. Definitely if he is making threatening/advancing movements. And then if he does anything other than what I tell him to do he's worm food.
On another note, all this Mass bashing reminds me of one of my favorite bumperstickers: "Ted Kennedy's car has killed more people than my gun." Baahahaha. Is he dead yet?
