Many Europeans that think Americans are gun-happy forget that in many parts of America, even in the 21st century, Americans deal with some very dangerous threats from animals. The American south, arguably the most pro-gun area of America, also has a wide range of panthers, gators, bears, and worst of all, wild hogs. These kinds of threats don’t exist in the same way in Europe that they do in America. These animals have no problem coming after people if hungry or surprised by your presence. (And in the case of wild hogs, whenever they please regardless of hunger because they are several hundred pounds of roving destruction.) poisonous snakes can be a sudden and unexpected threat and they move faster than anyone with a knife. In the American South, rabies can also be a significant threat even in populated areas, making many wild and domestic mammals quite dangerous unless you know the animal well personally.
Even with all human threats aside, there are many families in America that owe their lives to the quick ability to take down a dangerous animal. A common phrase you hear in the American south is, “When seconds count, the police are minutes away.” The police aren’t constantly lurking around playing nanny because America is a big place. Plus, the overall culture prizes being prepared for your own problems rather than being dependent on others. If you’re outside and wild pigs come near, you’re not going to be alive long enough to call for help. A can of mace means nothing to them, so you have to be legally able to maintain your own ability to use quick deadly force.
