Gun people insisting that the word "assault rifle" only applies to automatic or select fire rifles (or better yet, doesn't apply to carbines or submachine guns) because it's a fixed definition set by Adolf Hitler himself (seriously, it's a calque from WWII Germany) is a tired and irrelevant argument.
If we're gonna be sticklers for definitions, the 1994 assault weapons legislation made a strict legal definition, and that's what most people mean when they're describing that.
But whatever you want to call two-handed firearms with detachable magazines, whether they fit the WWII definition, the Army field manual definition, the 1994 Assault Weapons Ban definition, or whatever else, I think everyone knows what people are talking about. Even if it's technically a carbine or a submachine gun or a pistol with a foregrip.
We're not negotiating a legal document, we're just talking about gun culture generally on an internet forum.
