There are plenty of things possible in one language and not (yet\anymore) in another. I don’t see what does this have to do with any kind of demonization.

Pick a differential, declare that it is a unique good/bad indicator, and then work it into your propaganda. "In Chinese, the word for tragedy is the same as the word for opportunity" to imply Asian businessmen are naturally predatory. The "red heads have no souls" meme, used to denigrate the Irish. The entire field of Phrenology is based on picking differentials and trying to explain your way backwards into why it proves some racist theory.

Its a boilerplate technique for alienating, mystifying, and ultimately demonizing an outside group.,
