Over the past 40 years, I’ve been paid to write more than two million words. Sooner or later, every one of them came back to the issue of guns and gun-ownership. People accuse me of being a single-issue writer, a single-issue thinker and a single-issue voter. It isn’t true. In a world where there’s never enough time and energy, I’ve chosen to focus on the one political issue which most clearly and unmistakably demonstrates what any politician — or political philosophy — is made of, right down to the creamy liquid center.
