While your beliefs are certainly valid, and even reasonable, you have to remember that often, violence may be the only solution for violence. How many nations have earned their freedom from tyrannical governments through wars (or revolutions)? Many, ours included. As far as problems solved by guns go- you are incorrect in saying that no problems have ever been solved by a gun. What about World War II? Did Hitler seem a reasonable man to you? Could you have changed that hearts and minds of millions of nationalistic Germans following a super-charismatic leader? While it's true that violence is a negative way to make change, don't fall into the trap of believing that it cannot solve problems.
