A gun nut with an arsenal. You dont stockpile that sort of deadly weaponry because you are a stable balanced human being. Most of the gun nuts I've met (and lets be clear its not the hunters, people with one or two in the house, etc) are almost to a person (they are in my experience all that way, but lets be kind) conspiracy theory laden nuts. Believing whatever conspiracy it is they happen to feed off is irrelevant. Its a sickness. Stockpiling weaponry is a sickness. You stockpile it because you believe you will need to use it in the immediate future. I believe that is his reason. An unhealthy obsession with deadly weapons and likely couldnt wait for his dream apocolypse to come round. Just decided to go start his own.
