I don't stand in the way of anybody owning guns but I consider them useless even now. All I could do would be get myself in trouble. The odds of me being invaded by armed men is extraordinarily low and the odds of my winning the gunfight even lower and the odds of my injuring a neighbor or a cat are certainly present. I'm a treasure-trove of exotic, noisy non-lethal weapons. A burglar, at least a slightly better possibility than an armed robber, will get the crap scared out of him and will exit rapidly.
OTOH, if they're one day late with my SS check, I'll be marching with my fellow geezers carrying (borrowed) muskets as we begin the long trek to Washington DC to overthrow the Treasury Department.
