Strong disagree. Anyone who knows how to operate their weapon and is willing to use it is a formidable threat to all but the most trained and determined invaders. The level of accuracy needed to hit a man sized target inside a house with a long gun is really low. Low enough that if you miss the problem isn’t that you aren’t yet skilled in the art of aiming, it’s that you didn’t make sure to aim at all before you pulled the trigger.
The bigger barrier is psychological. If you can’t get yourself to take deliberate aim on another human and pull the trigger knowing what will happen, then a firearm might not be useful. If you can do that though, the mechanics won’t be a problem except in the difficult cases.
