The strongest argument against the 2A is your average gun owner.

Why buy a gun if the intent is not to use it?

For the vast vast majority of people who buy guns, that intended use is self-defense.

Where most go astray is they are akin to being house poor - they buy into the brand queen influencers, buy something that's overpriced or at the max of their budget and is way more than they need and simply stop there, never spending another cent on training, proper storage ect. For far too many, having the gun seems to be as far as they think they need to go to be prepared and competent with a deadly weapon.

I can't tell you how many times I've walked out of a range because a bunch of goobers show up in the lane next to me, uncase a tacticool AR (usually AR pistol) decked out with light, optics, brown furniture on a black frame with punisher skull magazines and start peppering a target 10 yards in front of them as fast as they can pull the trigger. The only positive I've ever found in it is that those are likely the idiots who think MAGA is going to go to war against Libruls and that they'll be a key player in them "winning."
