Try using this video as a lesson starter, without giving context. It makes a solid point when choosing and using words in writing. Aligns well to CCSS Anchor Standard 3: Apply knowledge of language to understand how language functions in different contexts, to make effective choices for meaning or style, and to comprehend more fully when reading or listening.
To further push rigor, ask students to critique the video (and some of the comments) for improvement in clarity, and even point of view.
It's alarming that such a simple video about word choice would illicit such impassioned dialog. Ahhh the power of words!
