Though I am somewhat sympathetic to your cause, I completely disagree with this line approach. Individual firearm ownership is a right and mocking those who choose to exercise that right, or worse, suggesting we take that right away only polarizes gun owners even more. 

The reality is that until we lower the temperature on this issue and stop attacking the very idea of firearm ownership, we only sound like an NRA characterization of the evil liberal progressive gun grabber. 

The fact is that there are large swathes of this country that still use firearms as tools. I grew up in rural Iowa and the .22 rifle and 12 gauge shotgun we owned were(and are)basically required tools for farm life. Millions of people hunt, and use firearms for recreation in a responsible way. These people are not the problem but your rhetoric really does sound like a threat to their way of life.
