I told my husband I’d feel safer if I got a gun and learned how to use it. He said he’d feel safer if I didn’t.
Having tons of armed people might not work out well.
Tangentially, I’ve seen several armed guards standing around lately. One at a drugstore where homeless hang out, and two at banks. I’ve sometimes thought that must be one of the most soul crushingly boring jobs ever. If those guys were to snap one day ...
Your husband is WRONG, and we already have tons of law abiding armed citizens around. It is the criminals that will always get guns that are the problem. Having more legallly armed, and trained citizens is a very good thing.
As Rush said, take a course, but first go to a range and rent a gun WITH an NRA instructor for a hour or so. You will be surprised that you probably can shoot pretty well. It will also take the mystery out of guns which are nothing more than a tool to launch a small projectile. There are many, new female shooters at my gun club, and they shoot well, get training, and practice. It is also a lot of fun.
