The author was a nutjob from the left wing anti-gun school. You ignore that while we do adapt to changing times, it is not to take away rights, but to add to them.
For example, the nonsense that many on the left spout off such as: 'well if people are supposed to be armed as well as the government that must mean you want people to be able to buy nukes'
The founding fathers gave us the ability to amend there work as that is how we make changes to the Constitution. If the lunatic left wants to change the second amendment via another amendment to the Constitution, they are welcome to run on such platforms and to try and do so. They have that right.
This is plain and simple about anti-gun nuts wanting to rant and rave about how guns are the evilz. You don't see them trying to ban auto's which we see far more involved in death than we do guns. Almost 42,000 per year die because of those evil cars.
