Well, I considered it to be prudence on my part to leave a place where a person had a gun on him. I was afraid, no joke. If you've ever been menaced by a person with a loaded gun- you might feel differently yourself. I have been, so I make no bones about not wanting to be around anyone with a loaded gun. I have also been in a situation with an incompetent person (incompetent as in not being able to handle a gun) and the gun was dropped and went off, so I have nothing to do with guns, and would rather not be around them.
I am not against ownership of all guns, but I am against ownership against automatic and semiautomatic weapons.
