Some namecall. Others condescend. In either case, you usually you reap what you sow.

In any event, you seem lost. The problem with a .223 is that it delivers a very high amount of muzzle energy (and high killing power) yet maintains a very manageable amount of recoil when fired from a rifle platform.
People say the same about a .243. Very manageable recoil, Yet it's inarguably more powerful than the .223. On the other side, there's the 22 250. Recoil difference is fairly negligible in the real world. To the point it has more to do with gun design than cartridge. So it becomes a pretty awesome coincidence that people only want to ban the one that's in the news.

YES. That's the whole damn design strategy of the NATA5.56! Jesus you are ignorant.
Reaping, Sowing. etc etc

A .223 has much less recoil than a .308, but still delivers a very deadly projectile.

A .22 is deadly, but not to the same degree as a .223. A 22 is a very small projectile (30 grains) fired with a muzzle energy of about ~150ft*lb. A .223 is a small projectile (60 grains) fired at a muzzle energy of 1300ft*lb (10x the energy).

The difference?

A .22 will put a small, neat hole an inch or two into your body (not a good thing, but readily survivable even without prompt medical attention).

A .223 will enter your body, yaw (tumble end over end), fracture and SHRED your insides like razor blades. Very similar to what a hunting round (a common use for the .308) is designed to do. The biggest difference being a hunting round expands and then shreds, whereas a .223 does not expand due to design (to comply with international treaty). This lethality is all done with a manageable recoil in a .223 platofmr, the, as you call it, sweet spot.
There's a reason a .22 isn't legal to use on deer in most states. Same with the .223. But the .243 is generally considered ok.

Fact of the matter is,the difference is most .243's look like this:

And when a crazy wants to go shoot a bunch of people, he wants to pick up a weapon that looks the part. It sure as hell ain't because he's done detailed ballistic study on 223 vs 22/22-250/243. 600 pound gorilla alert.
