Curing every single man, woman and child in America of "mental illness", including people who don't seek nor want treatment, for no cost, to a level far beyond our current medical knowledge, in less time than it takes to buy a gun and so completely that they will never relapse, all so that the public can be indiscriminately sold semi-automatic weapons without any balancing of risk, is not nearly as reasonable a solution as the pro-gun community pretends it is.

Even if that paradise could be built, it's not the America that people are living in now where domestic terrorists, armed with semi-automatic weapons and political views functionally identical to most of the pro-gun community, are routinely firing into crowds of people with legal, easily acquired weapons that are perfect for firing into crowds.

So how about this as a compromise: America can adopt strict, risk-based gun laws in line with the rest of the world today to address the maximising of damage that is happening now.

Then, once you've finished building your air-tight mental-health-for-all system, you can have your dogshit gun laws back.
