Ah yes, you've got things mixed up. You're just assuming this to attack the left and neoconservatives. Look at what the definition of Nazi is and you'll see the truth.
The historical definition says as mentioned on the image "a member of the National Socialist German Workers' Party."
And today's definition says "of or concerning the Nazis or Nazism."
Put it this way that those who stand for or are similar in the policies/beliefs of the National Socialist German Workers' Party are simply Nazis (just because the Nazi Party call themselves socialist doesn't mean they are socialist because the Nazi Party was very dishonest).
Have a read of this article of an organisation website and summarise it for me...
