Leftists are building and learning new political terms and new political things.
Mostly this is a good thing. But we need to strategically incorporate words in ways that are inclusive and/or advance our goals, and are not counterproductive. See, for example, Sara Lynn Michener on some cases where use of new language can be counterproductive. Michener’s article is far from perfect, though perhaps that’s some of the point.
With that in mind, I’ll boldly (and at least somewhat seriously) propose this flowchart for deciding whether you should use political terms you’ve just heard.
