That's years old right wing propaganda spread by the likes of Alex Jones for years. They use the 'socialism' in "national socialist" (part of the term Nazi comes from) to argue so, ignoring the fact that anyone can make a name whether or not it's true. If any socialist plans were made by the Nazis, it was of course racist first; only the in group gets any benefit.

These are old ideas that were niche at first but have been moving out into the public as the right shifts the Overton window. Stuff we'd dismiss at ridiculous crazy yelly conspiracy man is now mainstream even with people who might not want to be associated with Jones.
