Ok, yes some of these ladies have poor form and would be fine with some proper training.
But the truth is that an AR is far (FAR) easier to hold on target and fire than any shotgun on the market.

Your opinion is correct, if all you take into account is the guns. However, if what you try to do is prevent the crime, a good, advertised alarm system trumps ANY gun.
Mikey: With a good alarm system you huddle and hide in the bathroom hoping that the police get there in time. When you have a gun you huddle and hide in the bathroom not worrying about whether the police get there in time or not.
With the alarm system the police find the homeowner’s dead body in a hallway and start the paperwork.
With a gun the police find a startled and shaken homeowner standing over the body of some waste of flesh and start the paperwork.
See the difference?
