I am also a realist. I plan and prepare for the unexpected, so I guess I could be called a prepper/survivalist. I don't stockpile food or anything like that. But I do have skills and items that will help me survive. I started by asking myself, "what would I do if I didn't have all of this? Food, water, clothing, stores, money, everything...what would I need to survive?" That's where the list started and the preparation began.
I don't think anything will happen but I am always prepared for the possibility. I think we take too much for granted and depend too much on outside sources to get us what we need. We have forgotten how to do for ourselves. Yes, I buy my food, clothing, etc. at the stores and I love this luxury, but if it all went away tomorrow, I wouldn't panic. I'm prepared.
And yes, preppers will be prepped for defense. I am prepped for defense. I would shoot a person trying to break into my home to steal without any questions, regardless of their reason. Knock on the fucking door and ask for what you need!
I was just offering a new perspective (not necessarily mine) and I wanted your thoughts.
