Possibly when the Nazis stop considering themselves right wing?
"Left" and "Right" have always been defined on the spectrum of those who want to overthrow traditional institutions vs. those who want to preserve them. A monarchist is right-wing, even when the monarchy is very anti-liberty and anti-individual. An anarchist is left wing even though they advocate a dream world with no governments.
By this definition, Fascists and Nazis were Right Wing in that they opposed the labor unions, returned property to the aristocracy that was seized from them under the Weimar Republican, officially opposed atheism (regardless of their leaders' personal beliefs), and won the support of industrialists and the military elite of their countries. Meanwhile, Communists imprisoned and executed industrialists, aristocrats, etc. while putting labor union bosses in positions of power.
By the traditional definition of Left and Right, it makes perfect sense for Fascists and Nazis to have an affinity with the Right rather than with the Marxist or Anarchist Left.
