Sorry, it's a common mistake (isn't it?). I haven't been brainwashed, I just live in California. Pretty much anything semi-automatic with a detachable magazine (not the box kind, I don't think) is defined as an "assault rifle" here (and is therefore illegal). I'm just applying terminology that is commonly used (and is understood by most everyone) where I live.

Move to California and no one will care what you call your AK, they'll still brand it an illegal and highly dangerous firearm that you can't have. Apparently, violent crime is prevented if law abiding citizens aren't allowed to own such firearms. All gun owners are treated like criminals here...I can't even buy a box of ammo without being fingerprinted.
