This came about over several PSAs that note fully automatic weapons are "effectively illegal" for Americans to own or "virtually banned" or similar phrasing, which was then challenged by pedants who wanted to argue for "highly restricted" or "complicated" to acquire.

Folks, no sound bite or PSA can ever be 100% accurate.

For example, the Earth is not a perfect sphere. There's both an oblation due to centrifugal force, and two other bulges that interrupt even that shape, to a ratio of .00005.

And of course, centrifugal force doesn't actually exist.

And no one cares. The Earth is a sphere, near enough not to matter to anyone.

As far as the fact that full auto are not totally illegal to everyone in every state:

I could cite NFA 34, GCA 68, NDA 1916, FOPA 86, define every term from pre-May to post-May to SOT, list the relevant state statutes, describe Form 1 and Form 4, explain the history behind the .00033% of firearms in this country it relates to, by which time I'd have written a fucking book, which would be outdated and in need of a second edition before it hit Kindle, and cause everyone's eyes to glaze over, and as you can see, even in THIS thread, people who want to know are confused and underinformed of the details. Then, as noted, I could mention the increasing price, which is a hindrance to probably 95% of the population off the bat.

Statistically, no one cares about details that fine. They don't fit in an infomercial, and full auto are effectively illegal for 99.99986% of the population.

Done.
