@JCPA – Don't put words in my mouth. I would never say something like "guns don't kill people".
Please try to understand what I was saying about gray areas and cultural differences and try to see things from other perspectives, as INFJs are supposed to.
First point: While I lived in the city I was against having a gun. I saw fetishization of guns there, irresponsible gun use, and threats and crimes with guns. I've had friends die from guns and violence, and seen people die from violence where everyday objects (like chairs, or cast iron skillets) were used as weapons. (And yes, I stepped in to help save a life in many cases, unarmed except skills I picked up in a dojo.)
Second point: The gun owners I know are currently speaking out for stricter gun laws, longer waiting periods, background checks and mental health checks, compromise with gun laws, and for semi-automatic and automatic weapons to be outlawed. However, they want the right to own a gun if one is qualified and passes the checks, to remain legal. This won't work unless our country gets serious about providing health care, including mental healthcare, because mentally ill people can still access illegal guns, and that wouldn't change if gun ownership became completely illegal. Reasonable and responsible people who want to own guns are not against these measures.
Third point: "A tool is a device or implement, especially one held in the hand, used to carry out a particular function." – The function of a gun is for protection. In rural areas, one takes a gun when going into the wilderness. Most of the time, wild animals are not a threat, but sometimes they are. My last choice would be to shoot anything, but I want the option, and everyone I know in my area feels the same way. Nobody I know who has a gun even hunts, btw, which is a legal function of gun. I'm vegan, and some of my gun-owning neighbors are vegetarian, so unless you're vegan/veg, too, you probably end more lives than we do on a daily basis.
Fourth point: Domestic terrorism must be addressed. While I am for compromising on gun laws, I admit people who want to commit these atrocities will find a different way. Pressure cookers have been used as weapons. (Can the news also please stop teaching people how to make bombs?) Mental health care is needed in this country. People with criminal backgrounds and metal health issues slip through the cracks too easily, and this needs to change. That said, our prison system is a disaster, too. We also need to stop glorifying the killers. Their names should not be in the news, or made public. I don't know what else to do, but if we all put our heads together, we can come up with more options to minimize the tragedies that are now part of American culture.
