Let's see- short stroking, MASSIVE recoil and muzzle blast, dangerous over penetration....so how do you figure that?
"Massive"??? If you mean lots more than a .223 I'd go along with that. Over penetration? Up until the advent of frangible bullets shotguns were considered the least likely weapon to over penetrate. And short stroking doesn't apply if you're using a semi-auto, a bolt action or a single shot. And what about all those jammed 5.56 rifles I see at the range on a regular basis? I don't see many shotguns doing that.
I might agree that a AR is better for HD but a shotgun is absolutely more versatile. And with reduced power loads, a really good recoil pad and a little knowledge on how to hold a shotgun the problem of recoil all be but vanishes.
And what about the person that doesn't know they need to use a particular type of ammo to avoid much more serious problems with over penetration?
The shotgun has been the go to gun for hundreds of years actually. The breech loading musket was often loaded with what we would put in a shotgun shell. All of a sudden we're supposed to think it isn't practical??? I guess the fact that it pretty much tamed the world, conquered continents and fed generations should just be forgotten in a wave of hyperbole. A shogun saved my great, great grandfather from a bear, one saved my mother from being raped, and one saved my uncle from being kidnapped. They sure sound like a practical thing to have around to me.
