Good diagrams. Perhaps the easiest way to explain to a libtard is by substituting subject matter. Take for instance, this sentence:
"A well educated people, being necessary to the security of a free state, the right of the people to keep and read books, shall not be infringed."
Any person with a modicum of intelligence should immediately see this as an absolute defense of the freedom to own books.
Anti-2A arguments are among the most dishonest arguments in history.
