The whole point of this book is to support the 2nd amendment (right to bear arms) and the idea that free access to weapons make us safer from dictators.
However much I may agree with this I can't get past the fact that this book is very poorly written. There are passages where in a few sentences we jump from one scenario to another without much in between. E.g. 'john went on a ship, after a few months he arrived at planet whatever'. Yes really.
