Linguistic creep (or semantic drift) is exemplified by the use of terms like "art," which, once rigidly defined by culture and its relative merit, argued, today, "anything can be art" as beauty is in "the eye of the beholder."
This horizontal expansion renders the term ‘art’ nearly meaningless, and alternate categories must be delineated to allow critical judgment.
A similar expansion occurs with "violence/trauma" or "racism": if all things are racist (systemic racism) or any action can be deemed triggering, we must now invent new terms to respecify the attenuated definition, such as "anti-racist" or "pro-peace."
Words function symbolically. Once the categorical definition is expanded, it de-defines the word, rendering it useless as it ceases to point to anything. (The sign points to the signified (idea) forgetting about the signifier (object).)
Just as we can no longer recognize "art," as it is everything, the danger is to be unable to name actual racism or violence: the broadening spectrum dilutes the impact. Originally, to open a term spotlights unconsidered applications, which can be helpful, but once popularized as a tactic we must reinvent the language.
