The 2nd Amendment & Changing Times
Things have changed between the time of the founding fathers and now. On the one hand, the USA now has an extremely well-armed military force, while most state and local governments have well-armed police forces, and all of those forces are under the control of elected civilian leaders. On the other hand, the USA has a far higher rate of gun deaths and mass shootings than most citizens are willing to accept. Whether and how things should be re-balanced are open questions suitable for respectful debate.
