The problem of mass violence in the U.S. is more a reflection of contempt for the sanctity of human life than of a love for gun ownership.
In a society that reveres human life, gun ownership isn't a chronic problem. People who genuinely believe in the sanctity of human life won't take another life - by gun or any other means - unless it is absolutely necessary.
Not so in a society that views human life as subjective and revocable.
In a society that condones, funds, and promotes abortion and excuses euthanasia, human life is cheap. When a woman has a right to kill an unwanted child growing inside her simply because it suits her to do so, life is robbed of its value.
In a society that believes that a woman has the power to change the child growing inside her into an inanimate blob of tissue simply by decreeing that it is so, human life is something that can be dismissed by mere whim.
This "It's a life if I want it to be, and it isn't if I don't" mentality presumes that people have the right and power to play God with human life.
Likewise, if a husband has the right and power to prevent a hospital from continuing to feed his wife, thus starving her to death a la Terry Schiavo, the message is clear: life can be extinguished by decree and desire.
Then, there's the pervasive, gratuitous violence of today's entertainment and video games desensitizing America's children (and adults) to the wanton, wholesale destruction of human life.
People who believe human life is sacred do not extinguish it capriciously; they do everything in their power to preserve and protect it.
People who do not believe human life is sacred can be more prone to base life and death decisions upon emotion, convenience, and hubris.
Thus, when it comes to preventing mass violence, the answer is respect for life and self-control - not gun control.
