Re: "...Fuhrer is just German for leader..."
The German title Der Fuhrer does not directly translate into English as "leader"; many languages contain words and phrases which do not literally translate into other languages.
Fuhrer implies a supreme leadership; both in all matters spiritual, as well as all matters political.
As such it connotes a semi-divine saviour personality such as an avatar in Hindu mythology.
Many Nazis, past and present, make pull no punches when they give their testimonials praising Hitler as "the living Incarnation of G-d on Earth".
