Apparently you were not born in the United States and have no inkling of the 2nd Amendment to the constitution of the United States. If you were not born here you have no idea as to the right of gun ownership that is provided in the constitution, by the second amendment.
Even those that are not gun owners or gun advocates, understand the law of gun ownership.
This concept of gun ownership is difficult to explain and hard for those not born in the United States to understand.
We are not paranoid or cowards, by any stretch of the imagination. The constitution gives each United States citizen the right to own a gun. There need to be no other reason.
It is your options or choice not to have a gun in your possession for any reason. Most individuals would never have use of a gun for protection.
Individuals that reside in the United States possess guns for more reasons than self protection. There are many that own guns for hunting and collecting. There are many more that have a gun for these reason than self protection.
Your legal gun owners will abide by the law of the state in which they reside and if registration is required they comply and do so.
Of course you have your criminals that illegally have guns. They do not register their guns and in most instances steal them or purchase them on the black market.
I have been an avid hunter and fished since my grandfather would take me with him to fish and hunt. He gave me my first gun at the age of nine. He also instructed me on the proper use of being a gun owner.
In my family it is a rite of passage to be given your first gun, Even the females in my family are avid gun owners. Almost each member of my family own a gun both male and female.
In my family, we primarily use our guns for hunting and target practice, however, I am not oppose to protecting myself with it, if it become necessary.
You might feel safe, however, there are many individuals because of their economic situation, might not reside in such a safe neighborhood. They would want to have a means of protecting themselves and their family if someone decide that they would want to invade their personal space and take things that do not belong to them. Their gun is a deterrent and place them on equal footing with those that is trying to rob or kill them.
I hope this has been of some benefit to you, good luck.
