I use “New” or even “Neue” to distinguish the Nazis that claim to represent Jews and are genocidal towards Arabs, from the Nazis who claimed to represent Arians and were genocidal towards Jews (and Roma, though “curiously” here in the West almost nobody mentions those).
Because the etnicity targetted by one group of Nazis is the “dominant” etnicity of the other, if I don’t do this some people confuse my anti-Zionist point with being pro-Zionist, especially given that the Zionists themselves will use Nazi as a form of slander against people who criticize them.
In summary: Neoliberalism.
