Please refrain from posting any more idiotic crap like this. You don't know what you're talking about.
I personally own the three guns I have for personal/home protection. My work takes me all around town into peoples homes in all sorts of neighborhoods. In a world where people shoot pizza delivery guys for $50 and kick in 80 yr old women's doors and torture/murder them for their social security money I want to be prepared.
Problem is I do know what I am talking about, In several threads including the most recent gun control thread on this forum I suggested many reasons, examples, compromises and answers to do with combating gun crime, the origin of why guns are at the heart of the USA and possible ways of reducing gun crime.
The reason stems from the second amendment, the process which calls for an organised militia which in fact is what your national guard covers, has been broadened to include the general public in case they themselves are called upon to form another militia, this has caused further problems as because a lot of people can hold firearms, there's a higher likely hood these guns will be used for crime, as well of course protection.
Due to how readily available weapons are, there's a higher likelihood that people suffering from mental illnesses will be able to get hold of them at a time where they are at their most weakest, thus terrible events are more likely to occur. This is at the extreme end of the scale though, at the lower end the average mugging in the US will result in a higher percentage of fatalities as well.
This all stems from the countries current interpretation of the second amendment which has been taken out of context by some, and extended to include the general public by others. Gun companies will not allow this interpretation to go away as they make a lot of money from it and via this money they fund lobbying groups and members of the government that are prominent in the republican party which is part of a two party system.
All this including other parts of history such as WW2, Communism, Assassinations, etc have lead to the US being highly paranoid.
I have other thoughts, but that's some of the key points.
