While a logical goal its not one that really resonates and has people ready to follow. There is a logical problem here. We cannot advocate for reform that allows "less" life to be lost even though it is the only attainable goal - correct me if I am wrong but there are still lives lost to gun crime in Australia.
The cry is "not one more life" You cannot get there. You cannot offer realistic ideas that result in less life lost because you come off as heartless when you are are willing to accept the logical limits.
