Your mindset is not a crazy thing, remember it’s not paranoia if people really are out to get you, in this case I think they are living among us.
My wife and I occasionally venture into Walmart, usually really early figuring the drunks and deadbeats are still in bed, I always know where the exits and try to stay award of my surroundings at all times.
One of my favorite sayings, and so true. The Left particularly likes to accuse people of paranoia, so that only makes that saying more meaningful. (Kind of like the Soviets who classified people as mentally ill in order to confine them)
