And there's the rub. Lingo isn't inherently evil, in fact it's necessary to get through day-to-day life. You can't refer to every tool you use on the job with a short sentence explaining what it is, you say it's name and the people you work with know what you're talking about. The only time lingo must be avoided is when talking about something you're familiar with with someone who isn't to avoid putting them off or confusing them.

The real danger is people not realizing how (contrived, constantly changing) lingo can be used to manipulate them, specifically how it drives tribalism and the "us versus them" mentality. This is especially important given how political movements and other groups behave online, and how prevalent this tactic has become over the past decade.
