I saw this in a very short period of time with the SJW term "cultural appropriation." In 2014 when I first heard the term, the internet dictionaries gave it a neutral definition of an exchange or adaptation of a cultural element. About a year later when I went to look it up again, the neutral definition was erased and only the "muh stealing/mocking another's culture" definition remained. Orwellian as fuck.
WW2 truly was the start of Western Civ's new Foundation Myth.
