That's a simple fact. "Imperium" is Latin. I see no reason at all for you to bring that word into the discussion.
Anyone who speaks of the Holy Roman Empire (whether directly or by metaphor) in the German language will inevitably have to utter the word "Reich". You'll have to live with it, Olog. Attempting to gin up offense at any use of the word "Reich" just makes you look ridiculous.
Good day.
It's also German. With some asking me how much German I know, that's how it got put into this discussion—and that's apart from the phrase Imperium Romanum Sacrum.
"Imperium" is Latin
Not knowing the history of the successive Reiche makes one look ridiculous, actually. You do know how the first Reich was formed, I hope? Were you aware that we were fighting the Second Reich during WWI? Why would the leader of Germany from 1933-45 lay claim to the orb, scepter and sword of the aforementioned Reich? and why has the Reichskonkordat remained unbroken till this day? Add to that the resurgence of antisemitism across the continent. Doesn't take long to assemble this puzzle.
