The second amendment has nothing to do with self defense or hunting.
Would our forefathers want us owning AR15s? You betcha.
Oh yes it does. Because indeed, defending oneself is NATURAL as is surviving by finding food.
Yes, it was also recognized that groups of people might defend themselves against their own government, but that does not preclude enshrining basic criminal defense or hunting.
These are all natural rights, and the point of the BOR was to ensure they were recognized and not ignored/violated.
