“SHALL NOT BE INFRINGED is absolute. There are no words modifying that language. “
You might say that they are modified by the preceding words:
“The right of the people to keep and bear arms”.
What is inside that right and what is not?
Can the law require the return to its true owner of a stolen firearm you are keeping and bearing or can you claim your right to keep and bear arms allows you to keep and bear it and a law requiring its return is an infringement?
What about five year olds? Are they covered by the right of the people to keep and bear arms? Is a law saying a parent can forbid them to do so an infringement of their right?
I believe we must promote a better understanding of the right rather than just shouting “Shall not be infringed”. We don’t need to convince those on The Right, and we can’t convince those who support the Far Left, but there are a lot of people in the middle.
