Showing that you have the means to defend yourself does not cause violence....
You must believe guns are bad, and that they cause violence.
I owned my first guy when I was five years old. That's not the issue.
Whips are fine for moving cattle too - but taking one to a San Francisco bath house called 'Beat Me' might not be a great idea. Same for bringing a gun to an Occupy site - just don't want to make the dregs that happy.
