mjw16,
Actually, I do carry a gun in all those scenarios, though obviously most of the time it is of little use. But it's there nonetheless in case it is needed - - e.g. while flying it's there in case of a land-out, mostly for predator defense.
Risk of an accidental discharge? It's likely you are not conversant with the mechanics of firearms. When not on the bike, I carry a SIG P229 with a round in the chamber, hammer down. As long as it remains holstered and the trigger is not pulled (6-7 lb pull required) it not going off unintentionally, not even if it's dropped on the hammer.
Firearms training, for cops too, has improved dramatically since I was on in law enforcement. At 64, I'm more proficient with a handgun now that I ever was, though obviously I move a little slower.
I suspect your opinion about all this won't be changed by me, nor mine by you. That's just fine, and as long as you respect my rights, including my right to defend myself. You may be assured that I'll respect your right not to. The T-shirt thing was tongue-in-cheek and not intended to offend you. I appologize if it did.
Remember, never point an unloaded firearm an anybody.
all the best,
