I heard that Brent Spiner (aka Data from Star Trek) went on a little Twitter rant about gun owners being "Dangerous", so here's a good article about why they aren't.

“The Gun Is Civilization” by Maj. L. Caudill USMC (Ret)

Human beings only have two ways to deal with one another: reason and force.

If you want me to do something for you, you have a choice of either convincing me via argument, or force me to do your bidding under threat of force.

Every human interaction falls into one of those two categories, without exception. Reason or force, that’s it.

In a truly moral and civilized society, people exclusively interact through persuasion.
Force has no place as a valid method of social interaction, and the only thing that removes force from the menu is the personal firearm, as paradoxical as it may sound to some.
