All of this rhetoric is nothing new. Same thing happened in 2008-2009. Yea, we had the same "Chicken Little" nonsense. Ammo went into big time shortages etc. What happened, basically nothing. In my state gun laws improved for the gun enthusiast. The old law of one gun a month sale was repealed, ccw permits increased dramatically and very easy to get, and finally even Pellet guns got approved for hunting. So what caused the great ammo shortage? Well it was not the President, it was not congress, it was a frantic, over the top frenzy consisting of a enormous amount of hysteria and rhetoric, and fear by the gun owners themselves. The NRA themselves were deluging mail with so much crap that one even forgot what the NRA was about.
It is the oldest trick in the world. Use fear and propaganda to move the masses. Both sides are doing this, and it does not work for either side. Only for the short term. In reality, the sport is growing and will continue to grow if and only if gun enthusiast take a platform to have intelligent discussions and not just try and jam their views down the other sides throat.
