there is no good reason to ban guns, this is the problem. When we live on a planet where the military industrial complex rules, and where we have no privacy, decreasing rates of private ownership of all things, cars you no longer own, iphones you never owned, jobs being taken by robots, there is an increasing argument to support the widespread redistribution.
However, there are lots of guns in the world, and this hasnt prevented our lives being crushed regardless, so perhaps they are still pointless since it takes a special headcase to actually use one as they were intended
