Alt-Reich
Alt-Reich: An Intentional play on the word “Altreich”. which is an actual German word meaning Old Empire and can refer to Germany’s pre-WWI territories or even it’s territories as the Holy Roman Empire, i.e. the countries Hitler tried to take back.
The Alt-Right’s current message and tone very much resembles Hitler’s infamous 3rd Reich, and thus in slang terms could be called the “Alt-Reich”.
