The main reason we can't get decent background checks on gun sales, magazine/ammo regulations, and some kind of curb on irresponsible storage or handling of firearms, is that the advocates of such measures are publicly represented and characterized by a chorus of shortsighted authoritarians who see no problem with having government agents walk into people's houses to inspect their storage and handling, firearms they see no use for confiscated from their owners and the rest made bureaucratically as inconvenient as possible, and a Constitution they can't seem to read straight interpreted as allowing governmental power to impose anything some authoritarians think will be of net public benefit in their eyes. We have people actually advocating that guns be confiscated from their owners to slightly lower the risk that other people will commit suicide - "public health". These are the people who have the police pulling us over and fining us hundreds of dollars at their convenience for not wearing a visible seat belt, arresting and fining people who attempt to float in inner tubes or swim in places or times without government approved lifeguards watching them, restricting pain medication for injured walkins in case they are faking it to feed a disapproved addiction, requiring helmets on bicyclists and lifejackets on canoeists and airbags in dashboards at personal expense and hassle, and so forth. I don't want people who think like that given power over any aspect of my life. When they get the cops backing their latest efforts to improve my health, I'm afraid of them. And that's why so many of the great majority of US voters who favor background checks and similar common sense gun regulation nevertheless oppose so rigidly the actual political efforts to establish them. The well has been poisoned.
