Don't forget, they have been putting NAZI's into socialists, equating them with communists, for a while now. Forgetting that NAZIs had a massive war with the Soviet Union- as they thought communism was deathly evil- and that it was the second time Nazis and communists fought (Spanish Civil War).
It also ignores the fact that the difference between single payer healthcare and what we have now is that the current system rewards the money launderers by letting them make a ton of money doing nothing. Well, they do something- tell you where you can and can't have things done, what things you are allowed to have done, etc. Single payer will include all doctors (as it has to) and all procedures (as it would have to).
But explanation is impossible to people who are too stupid to think on their own. Easier to just go on the National Socialist.... and pretend that Hitler made a socialist system so that we can all fear socialism for reasons.
