I understand what you are saying, and if you are uncomfortable with guns, that is a personal decision. At least you are able to determine, for yourself, what you are best suited for.
The answer to the question in your last sentence is "no one will". Personal safety is up to the individual. If an individual decides that their life is not worth protecting, then chances are, no one will think they are worth protecting either.
When the Jews were targeted for extermination in Germany, no one (with few exceptions) stepped in to protect them. That is why 6 million died. Today, Israel is heavily armed, and they allow open carry of full automatic weapons. Because they know that no one stepped in to help them when they were being persecuted, and they were nearly hunted into extinction. The sad, unfortunate, fact of life, is that your personal safety is in your own hands. It is nobody's responsibility to protect you, except you.
An armed security guard is not going to walk you to your car. They are not going to step over 50 bodies to make sure you are ok.
