Get a new hobby? One that doesn’t threaten everyone around you, maybe? Maybe one that’s just overall cheaper.
I have zero problem with hunting, target shooting, collecting. One poster here says they have 4,000 rounds; shoots trap every weekend, buys them on sale. Fine.
This dude had 26,000. That is a compulsion. He thought amassing ammo would solve something for him. Would provide him something he lacked. Probably something subconscious. Some deep-seated fear.
As to the rest of us, it solves nothing legitimate, certainly nothing the Second Amendment was directed toward.
