I had long wondered why conservatives would prefer an AR-15 over a shotgun when it came to home defense since for stopping power the shotgun set up correctly would be brutal. Personally, I think that an AR-15 has never been intended as a weapon for defense but purely for offense when it's necessary to fight off the likes of a Liberal Joe Biden who they think already stole one election from them as he attempts to steal another...ask Trump...he'll tell you. No, if this was about home defense a shotgun would be the choice any day of the week...

You pose far too many fallacious assumptions, Pete, any firearm can be used for defense, even an AR15.

Combat troops, armed with automatic weapons, are trained in both offensive and defensive tactics.
IOW, they use the so-called "assault weapon" to assault or to defend.

A semi-automatic firearm - pistol, rifle, or shotgun - is versatile, it can be used in a wide variety of situations - target shooting, competition, hunting, self defense, even against tyranny.

I use a 12 gauge pump loaded with 000 buck for home defense, and carry an M9 Beretta for personal defense.

AR15s have been used far more often in self-defense than they have been used to commit crimes.
Even youngsters have used an AR to defend their homes and family.
For one thing, kids can handle the light recoil of an AR15 compared to that of a shotgun.
