As a result of our Second Amendment right, Americans have spent the last several decades acquiring guns like some acquire clothes, furniture, cars, and smart devices. Most of the gun owners are law-abiding citizens and want to take advantage of the second amendment or simply have other uses for owning guns, like target practice and hunting. These people, I suppose, do have a right to purchase and/or collect guns although I really cannot imagine why they want to do so... as many of them have never fired a gun and never want to.
In contrast, we have criminals and those who want to break the law, who purchase guns and do so for the sole purpose of committing a crime believing that few people will stop them if they show these people that are carrying a gun and give them the impression that they are going to use it.
Most if not all of the people (those who commit crimes with guns) are mentally handicapped or mentally imbalanced or suffer from some sort of mental illness as killing others is not necessarily part of our survival skills. Although, all living creatures see survival as the key to life and should only be done under a certain set of circumstances... like kill or be killed.
Since this is our human nature, the second amendment seems rather pointless to our survival in the decade in which we currently live or will live and was probably not necessary in numerous decades of our past.
We should make owning a gun very difficult and we should increase the age to 25... although using guns for other purposes such as target practice and hunting could be accomplished under the age of 25 and with the supervision of someone over 25.
We should also make the punishment for using a gun while committing a crime very steep so as to discourage people from using guns for that purpose.
Civilized societies do not need guns as they have a police department for protection internally and a military for protection externally...
However, each society should be able to use guns for recreational purposes.
Of course, this is just my opinion... if I had my way, I would remove the second amendment except for reaction unless you want to remove that part out of the constitution as well...
