I think you are prepared! For what? I have no idea!
Wow! I’m the minority here. My guns are for entertainment and hobby. I didn’t buy them for protection. I live in a decent neighborhood and I do have dogs that will give me a bit of warning. I will relocate if I have to watch my back all the time.
I do sometime have the fear of confrontations that might get out of hand, but the possibility of shooting the wrong person keeps my guns away. And it prevents me from escalate problems.
I do want to get a big truck just incase the guy next to me makes a blind lane change or the heroes that slams on their brakes because they didn’t like me tailgating.
You might be asking the wrong group of people. It's like asking the UFO forum if wrapping your head in tin-foil every night is paranoid or not.
