Sorry, I was taught the same drivel you were. That isn't the interpretation of the second amendment until 2008. I've already posted it in this thread multiple times, with SC statements and decisions that utterly support what I said. The second was never meant to prevent the states or cities from regulating or restricting firearms, and was written ONLY to protect the federal government from doing it, as noted multiple times over the ~200 years of case history, until 2008, as I already noted.
