Anyone familiar with the "actual terminology" should recognize that it derives from the German STG, not from American Democrats, and that contemporary usage includes semi-auto variants marketed for civilians. If you do not approve that usage, then don't use it. But you do not get to dictate contemporary usage of other people. Bottom line is blaming Democrats for contemporary usage(including usage of manufacturers) is ignorantly hateful, nutjob behavior.
Apparently you have a pretty strong political defense point set up here. Let's recap.
The root argument is based in my making a distinction. There is no opinion or need of political affiliation to make this distinction, only honest understanding of the subject matter. An "assault rifle" is a term with an actual definitional criteria. If X does not meet that criteria it is not an assault rifle.
Now with that absolutely non-opinion apolitical statement made we come to assault "weapon". This portmanteau is generally considered to be the creation of the rabid gun control advocate Josh Sugarman. It's creation was steeped in intentional deception from the start.
Assault weapons' menacing looks, coupled with the public's confusion over fully automatic machine guns versus semi automatic assault weapons anything that looks like a machine gun is assumed to be a machine gun can only increase the chance of public support for restrictions on these weapons. - Josh Sugarmann
The terminology started as a left leaning use of wordage for the express use in advancing gun control. The scope of their definition is such that taking a "normal" rifle action out of one stock and putting it in another can change it into an "assault weapon".
The confusing thing to me is you don't seem ignorant on firearms but are reticent to call a spade a spade here.
