Of course, the thing to do is turn it around on the anti-gunners. Its a grand idea, reducto ad absurdum. Its better than grand, its the greatest--because it uses humor to illustrate truth.
For example, "Obama would require back-round check in the middle of repelling a home invasion." Just make a video of a woman trying to get approved for a gun purchase while hiding in a crawl space with her three kids and a madman beating on the door.
This is satire. It is highly effective. Think of Jonathon Switft's A Modest Proposal about turning "excess" children into food. This stuff is powerful. It changes public opinion. It shapes the future.
Think about it. What about a satirical sketch/skit where a principled Chief Thief forbids personal security guards for his two daughters at a private school. Or, decides to ride in a Yugo instead of an armored limousine. The possibilities are only limited by imagination.
What about a sketch about an anti-gunner who commits sepukku before the gunman gets to him. "Anti-gun activitist kills self moments before deranged gunman makes it to his office in order to prevent gun violence."
"Yes, Chet. John was solidly against gun violence. I was on the phone with him in the final moments. He told me that he was going to kill himself in order to prevent the gunman killing him. He said good-bye and I heard his gasp as he killed himself. Then, a moment later, I heard the pow-pow-pow of the armed citizen's gun engaging the killer."
Gotta admit that was kinda creative. Twisted. But, creative.
