I never changed my mind; the 2nd amendment was a restriction on any and all governments that would hypothetically create restrictions and regulations of citizens assembling a community militia. Since the passage of the militia act of 1903 and the ones following, the relevancy of the 2nd is akin to the 3rd; an artifact of post-revolution United States, a remnant of how the revolutionary forces defeated the Royal British Military.
The hilarity of saying that even though that is literally the words of the 2nd amendment.
