If we're going to allow assault rifles and fully auto weapons, then where does it stop? Since you feel like you need those weapons for protection/hunting, and that's you're sole reason for wanting to keep them, then what's to stop me for saying that I need a tank, some grenades, a few pounds of C4, a flame-thrower, and an over-the-shoulder rocket launcher for my protection and hunting needs?
Should I be able to have those as well? Would you feel comfortable knowing that the crazy neighbor next to you could have them as well?
