It would be rediculous to say it's immoral to own a gun, for a Monk, perhaps, for a Lay Practitioner, of course not! Not everyone is a Buddhist, not everyone practices love and happiness, in fact, it's quite the opposite when it comes to other religions/peoples. Think of your family, of your friends, and of your nation. There will be a time when you are given 'no other option' but to use violence to protect yourself, and your family.
To any who objects, I challenge you to meditate on it, on the scenario where your life, your families, and your friends lives are at risk, where the attacker is giving 'no option' other then to be a 'coward' or defend your own folk. It's so easy for people to sit there and say, 'Oh! Oh! It's so wrong! I would NEVER!", but then come the time where they are forced, really forced the choice, they would do the same, otherwise, IMO, that is a coward, someone who would let the lives of their loved ones be at risk because they are too afraid or even ignorant, to stand up and fight for the continuation of those who want nothing more then peace and harmony. Am I saying to not feel bad for the death or hurt to the attacker? No. I am saying use your logic and common sense.
The Smith family had just recently moved into their new home in the suburbs of New York City. Mrs Smith, a lovely woman and homemaker is tending to the house and three children tonight while her husband is off at work as a regular accountant for the Bank Of America. She is doing the dishes when she sees three men peeking into the window, and screams immediately. The attackers waste no time and quickly find the back door made mostly of glass, kick it in and rush after the Wife as she had just ran upstairs to get her children. She remembers the gun in her husbands office, only a room a away, and quickly takes it out of the case before returning to her children in the room of little Morigan, her youngest, at only ten years old. The sound of the mens footsteps as they come up the stairs can be easily heard, "You see that pretty little thing?! Ohhh, I can't wait to have fun with her!" "I saw her too! You cut the phone lines, right?" "You bet! There will be no help for this one..."
The three men, friends who had recently gotten out of prison, where they had met, months apart from eachother. Weeks ago they were drinking at the bar and came up with an excellent plan for some quick cash, robbing the homes of innocent folks. Two were convicted of grand theft, while the other, of multiple rape.
This is a very real scenario. Try going online, and looking at newspaper clippings/stories, of these very real scenarios, and tell me it's wrong to own a gun and defend yourself. The Buddha was a man of logic, of understanding. And he would understand a situation like this, would he be sad that it had to happen in the first place? Of course, but he would understand.
Everything that makes you, you, is the result of your Environment (Society, Culture, Family, Friends, Etc), Genetics/Biology (Your brain which makes the mind possible, Inborn diseases such as Down Syndrome, or even Psociopathy, etc), Thoughts (Everything you think affects your mind, and the person you are), Speech (Same as thoughts, but words affect your environment as well), Actions (Same as Speech), and the Elements (Earth, Water, Fire, Wind, Space, and Time).
