In case you haven't noticed, law abiding people are the ones being killed. So, please, spare me the platitudes.
This is true. And at some point, the number of law abiding people who feel (justifiably) threatened by a nation awash in some half a billion guns will outnumber the law abiding people who are too selfish to accept any restriction whatsoever on their hobby.
This is Oceander's point - be part of the solution now or be marginalized - and cede to the "other side" the content of our gun laws. More to the point, the absolutist position will soon no longer be political tenable for either responsible conservatives or Republicans. Indeed, the real danger is that the Dems will effectively use the absolutist position to smear the entire party, and gain political hegemony in the process. And then the RKBA will truly be at risk.
What are the solutions? Obviously, there is no silver bullet (pun intended), and, like most complex problems, a multifaceted approach is required. Some of the solutions proposed by the absolutists make sense, such as placing armed security guards in schools. But the hobbyists need to understand that a system of licensure, registration and insurance is needed for guns for the same reasons it is needed for motor vehicles. Guns and cars are both useful and necessary implements, as well as potentially deadly. (Indeed the purpose of a firearm is to be deadly - it is, for example, the equalizer for a small woman being threatened by a large man.) But a regime of insurance, as it does with cars, encourages both responsibility and safe practices and creates a system of compensation for the victims of gun violence. If a legal gun owner must insure his arsenal, and be financially responsible for harm caused while in his custody, he will be incentivized to inventory his guns, keep them away from others, and notify the police promptly when lost or stolen.
There may be a host of other reasonable, efficacious solutions as well, that won't impact the natural and Constitutionally protected right of a father to protect his home and family against intruders, or a woman to feel safe when out alone, or a sportsman to hunt and shoot, or a hobbyist to collect his treasures.
But like Oceander says, if you're not willing to be part of the solution, the solution won't include you.
