In High Noon even Grace Kelly - a pacifist Quaker and sworn gun hater - eventually pulls a gun and kills somebody.
God forbid that any of us should ever have to do such a thing ... and in a perfect world guns wouldn't exist.
Unfortunately, this is surely not a perfect world.
Do Westerns glorify and encourage gun usage?
In my youth I handled and used guns extensively. Today I own no guns and haven't shot one in many years ... and have no intention of doing so.
