There's that completely predictable historical illiteracy we've come to expect from the modern descendants of the Nazis.
The National Socialist Workers Party was neither a party of socialists or workers - they were a radical right-wing authoritarian movement who had a really good grasp on propaganda, much like the modern Republican party.
In fact, they were so famously anti-socialist that Martin Niemöller's poem about the Nazis sending everyone to their deaths in concentration camps literally starts with the first line:
"First they came for the socialists, and I did not speak out—because I was not a socialist."
