The gun culture is a culture shared by people in the gun politics debate, generally those who advocate preserving gun rights and who are generally against more gun control. In the United States, the term is used solely to identify gun advocates who are legitimate and legal owners and users of guns, using guns for self defense, sporting uses (hunting), and recreational uses (target shooting). By contrast, the term is used differently in the UK and Australia, where it refers to a growing use and ownership of guns by criminals.
Is calling gun culture an “classic oxymoron” a consequence of confusing the two definitions? If you traveled in my circles you would find people who are productive citizens; who enjoy the shooting sports, who recognize it is their responsibility to protect themselves and their family from human parasites and predators and who value the protection of the Second Amendment. The problem individuals in College Hill Courts are a completely different group and should not be confused with the former.
