In the US we have the Second Amendment. The fascists have been the ones screaming and yelling about the Second Amendment, but the truth is that all Americans have the right.
Owning a gun isn't enough. Driving to Cabela's and picking up a vermin killing 22 is not enough. You should buy a rifle, a pistol, and a knife. (Bonus points for a shotgun) Then you need to train with said rifle, pistol and knife. Go to a range and shoot. Look for local self defense/hand to hand combat with knife classes and train.
I am not advocating for violence...far from it. But I am advocating for knowledge because owning a weapon and not knowing how to use it is a recipe for disaster.
PS: If you can afford it, buy suppressors. Especially for your rifles. Suppression for the common citizen isn't about stealth like in the movies, it is about protecting your hearing. Guns are LOUD. Much louder than you expect.
I wasn't kidding.
