Giving something a name makes it possible to talk about it. For example, the phrase "sexual harassment" was not common in English until around 1975. (See the screen shot below of how often it was used in print in English since 1900.) Before then, it was called "being fresh" or "making a pass". You can't solve a problem, for example, if something doesn't have a name.
Describe in detail at least one example where the choice of words you or someone else used to describe something had consequences.
