Secondly, your dodging. You conveniently did not quote the second part of what I said which pertains to your actual position; guns need to be eliminated entirely and people who own them should be negatively stigmatized to discourage ownership of firearms. Again, your priorities are horribly misplaced. Cars cause far more injuries and deaths to humans than cars. Yet you seem unwilling to put this same negative stigma on car owners. Why is that? The same policies you advocate could be applied to the automobile, hopefully eliminating the ownership of them eventually and thus eliminating the deaths and injuries they are involved in. Where are your priorities? It seems they are only placed on the ones that don't cause you a personal inconvenience.
Cars are designed to transport.
Guns are designed to injure.
Not anywhere close to the same thing.
However, society has built in responsibility for motorists..insurance.
Society needs to build in responsibility for gun owners..insurance.
As for stigmatizing it; That goes back to the OP. I was asked for a plan and that is the only way to stop mass murders who use firearms; make guns harder to get.
