Preparing for Low probability / High risk scenarios is what this site is all about. Having a bandaid when you accidentally snag your finger on the Printed circuit board at work while changing your network card is convenient but hardly a survival situation. OTOH having a trash bag to cowwer under on the lonely top of some mountain that you have been abruptly deposited upon out of your comfy airliner seat is a matter of survival. I willingly concede that you are far less likely to fall out of the sky than snag your finger at the office. That doesn't stop many of us considering and preparing for the possibility that we may someday find ourselves on that unlikely mountaintop.
I live in a rural area of New Hampshire, USA. There haven't been two muders here in 10 years. There have been tool related accidents involving all manner of power tools and recreational equipment. Table-saws, dirt-bikes and Hunting tools such as rifles. When seen as a power tool the gun is not more dangerous than table-saws. Accidental death and injury are roughly similar for both.
We will all choose the scenarios for which we will prepare ourselves. I don't prepare for Teotwawki because I would rather not survive that. I don't prepare for jumping out of a burning High-Rise (other than declining employment in large cities). If, as some on this forum do, you consider the potential (either probability or consequence) of a scenario wherein you need to protect yourself from the threat of deadly force something you would like to prepare for, then you will need to be equipped with something that can confidently counter that threat - firearms are a reasonable tool choice for such a scenario - if they are available to you.
The passions start to rise when the reasonable tool needed to prepare for a scenario which you feel worth preparing for are forbidden you by individuals or organizations who don't / won't / can't provide the equivalent level or security from the threat that they are preventing you from preparing for. It's all about being willing and able to take personal responsibility for your well being and security.
