I read something in my philosophy book about the inadequacy of language to describe things like emotions, etc.. The argument was basically that although you can brand something as "anger" as one specific thing, everyone's experience of it is different and unique, and can't be explained. I think this is essentially what you're trying to say. Your title/point definitely was provocative as you said, but I guess it was a good choice to get your real idea across and show that people are getting too stuck around the word and the definition rather than their own experiences. A worthwhile read definitely.
