It is even deeper -

Jewish article in Jewish journal with a lot of info about that very Jewish-specific thing written for Jews. But we could read it too. :)

So that man who addicted to that strange and very specific chimeric word writing scripts, templates and guides for article authors, celebrities, so-named experts and other propaganda stuff.

PS: Stefan Levandowsky who is a hero of articles about "vaccine refuseniks" is a long-term damage control pawn never used that word before, check him, read his "scientific" papers (one was retracted for defamation) - he is very interesting propagandist who for a long time try to attack freethinkers lying about them and their views and logic without arguing anything on the topic, but without any noticeable success. One of his papers - NASA Faked the Moon Landing—Therefore, Climate Science Is a Hoax, read and laugh. :) Find everything, including testing people on "SARS was made in lab" (yes, in 2013!), naming nowdays facts as "conspiracy theories" and excellent example of perverting real questions. And yes, you will not find that "refuseniks" in that paper or any other his writings or interviews. So, it is not his word, somebody else put it into his mind for the next "mission" of shitting on people who don't want to follow their fake narrative.
