Murders and suicides by the psychotic are more than a few dozen and should be a definite concern of a caring society
Background checks on guns won't prevent all murders and suicides by the psychotic. They'll prevent only those murders and suicides by -diagnosed- psychotics who, if they cannot obtain a firearm legally, will be completely dissuaded from their desire to murder or commit suicide. And suicide? We need to trade in our rights to dissuade people from killing themSELVES!? I'm sorry, but I would absolutely refuse to give up one iota of my freedom, to -RISK- one iota of my freedom, if you could guarantee to me that it would dissuade every suicide from now until the end of fucking time! I'm not down with forcing people to go on living, and I'm certainly not willing to PAY to force people to go on living, ESPECIALLY when the currency with which I pay would have to be my liberty. Holy fucking fuck fuck fuck I can't believe that you would even imply that such a trade would be SANE!
It's also fairly arrogant to assume that your definition of a caring society is something that I would strive to achieve. Why is it that liberalism has gone from "live and let live" to "live as I say live"? In short, fuck your "caring society" justification. That's not an argument, it's your own personal moral value. I don't see why I should be subject to it.
