See, there's a couple of very important concepts here:
1) That, in taking up and bearing arms, you, in that instant, become a well-regulated militia in the eyes of God and therefore can do no wrong.
2) That the God-given right to bear arms automatically confers the right to bear effective arms, meaning that if those who might cause you to feel threatened possess tank-killer Gatling guns, you, too, are entitled to possess tank-killer weapons of one kind or another.
Cool! I can legally build and weaponize my own drone!
