^ clearly making my point that cultural opinions dictate more than amendments (particularly ones held by SCOTUS).

Just to be clear, you're incorrect. The bill of rights was extremely clear, the intent was that every citizen should be armed. Recall at the time, the states had to call on citizens to defend their towns, states and country regularly. They didn't have money and needed the citizens to have their own weapons. For both personal and collective defense.

> The constitutions of most of our States assert that all power is inherent in the people; that... it is their right and duty to be at all times armed. - Thomas Jefferson

That said, there has always been a push from various political groups (all the way back to John Adams) who pushed to regulate arms in one-way-or-another. The point is, the reading itself is clear. If you read the various diaries, letters, speeches and publications at the time it paints a picture much like today. There are those who want a disarmed population fearing rebellion and those who demand an armed population. The group that won out on the amendment were clear: "There shall be no law regulating arms and you should be proficient in their use"
