Re: Guns or the people using them?
What about considering that since the Second Amendment was ratified, almost 230 years ago, the world has moved on.
When the Second Amendment was drafted, it was about defending against federal armies, not about letting almost anyone wander into a hardware store and tooling up.
I expect the Founding Fathers would turn in their graves if they realised they'd allowed a culture to exist where someone can easily (and notably legally) obtain the means to slaughter a large number of people simply because they disagree with their colour, religion, background or lifestyle choices.
For all good things that have come out of the USA, it's still a nation that refuses to let go of the past and accept that the world around it has changed.
