If the practice of applying a 'sin tax' was ever justified...
Defending yourself, your family and protecting your property is a sin?
When the greatest threat with home defense firearms is friendly fire or accidents, yes.
We tamed the frontier. The Indians are at peace. And since most people don't move into high-crime areas with their families where defense is a practical consideration, if you feel you need a weapon in order to live a life of peace you're a moron. Live somewhere else then where rampaging wild anials and people aren't such a concern.
