Yes, I would argue that we do live in a violent culture. We are not nearly as politically and economically stable as you seem to believe.
You seem to feel that disarming law-abiding citizens and victims would result in a safer and more secure society. I could not disagree more. There is no evidence that disarming the masses would result in a less violent, more peaceful society.
One person’s (erroneous, IMHO) beliefs about what makes a more peaceful society do not trump the rights of others to defend themselves. If you are asking others to give up their ability to defend themselves from violent criminals, you better have more than “feelings” to justify it.
The Second Amendment was written to preserve our ability to defend ourselves from a tyrannical government. The government is pushing the anti-gun agenda because they are worried about a revolution. They are not trying to protect the Joe Sixpacks of this nation; they are defending those who own or control the majority of the world’s wealth and power…and who seek to own and control an ever-greater share of our global resources. Study the history of wealth/income/power inequality and how these inequalities have almost always led to revolutions, and it will all become clearer.
