There are two causes of gun violence in the United States, one is the proliferation of guns, and the other is a culture of violence. The culture of violence is the main cause, and the proliferation of guns is actually a symptom of the culture of violence. The violent culture of the United States comes from its long-term foreign policy of asserting interests and resolving conflicts through force and violence. But because big businesses and consortiums can benefit from it, the Republican Party avoids talking about it and is only keen on playing with gun control issues.
