Nope. I have seen a HUGE increase in new shooters. Even if a portion of these folks vote it will have an impact.
There will always be horrible statistical outliers as far as violence goes. Guns or not. Honestly I think we have already seen a shift in thought in this regard with more folks talking about how do we stop or limit these folks from doing these things.
Sure there will always be true zealots looking to disarm the law abiding for their own gain but the reality is the left and right seem to be coming closer together in our thoughts in how to mitigate crime and tragedy. We are not there yet but seem to be heading in the right direction.
Take the smart gun thing. Of course it will be used in the short run to disarm the populace by those seeking to do so but in the long wrong (devils advocate here) would you turn down a 100% or at least as mechanically reliable as "dumb gun" arm that you could easily code to who you want but no others? Today, this second yes because it doesn't exist. Tomorrow maybe I dunno.
I am a firm believer in that there are people who actively want to take our rights away and they should be fought tooth and nail at every turn. I am also a believer that there are a great majority of folks who want pretty much the same thing, we just don't agree on how to get there. Those people seem to be moving closer together in thought. It is these people we need to discuss with as they, like us want to stop the next crazy mass shooting or stop the next innocent killed in a drive by, something we want as well. It is these folks that we will be able to hammer out good plans that may address the issues amenable to both sides.
Point is do your part. Vote, teach your new gun owners both the mechanics and politics and spend time to find the common ground with left leaning gun owners. The end goal should be to take firearms out of the equation totally so we can hold our politicians feet to the fires that matter to all of us vs these wedge issues they use to divide us.
So teach a new ahooter, have a level conversation with those that don't agree with you, do what you can to focus all of us on the issues that matter and their root causes and take guns off the list.
At the end of the day you win this fight through the middle ground, through voting, through focusing on the root causes. Not with rifles. You win by showing those around you that yeah I have a bazillion guns and ammo. Not because I am a door kicker not because I am waiting for an assless chaps mad max scenario, not because I am itchin to take on the big gov or blue helmets. Simply because you like to shoot. You store ammo because it's cheaper and more relaxing able that way. You keep a loaded gun or carry to provide a last ditch defense to your family or child no different then you would dive on top of them to protect them from flying glass in a storm or push them in a closet. Everybody understands these concepts. Use that to your advantage. Use your yuppie normalness to your advantage. Use your race, your sex etc to your advantage.
Shoot safe, be safe, always be an emissary.
My two cents but hey I don't know squat.
