"An armed society is a polite society."
Thus sayeth a bumper sticker favored by NRA types. And this is the sort of politeness which this self-appointed, well regulated, militia will enforce.
"Police: Pa. man shot for making noise during movie." Bigawd, he'll think twice before crossing THAT line again. You never know when Miss Manners has a weapon.
As well as using guns to teach your in-laws a measure of respect, they can be used to allow children to protect themselves from the unwanted attention of adults.
One thing is certain. The US should be one of the politest, most restrained societies in the world. Along with Mexico, Iraq, and Afghanistan.
