The irony of them arguing that you shouldn't own a particular gun because it was designed specifically to kill people is that the constitution doesn't protect recreational equipment, nor even weapons. It protects arms. AKA, military equipment designed to kill people. Designed to kill people in a military setting is precisely the qualification that makes it protected. A full auto belt-fed has more business being protected by the constitution than a recreational .22. I'm still for being able to own a .22 for sure, but the understanding of what an arm is has completely inverted.
