Asking somebody to clarify what they mean who is using a vague phrase is useful. Telling them to stop using a phrase that you personally don’t understand is not useful. Think of it this way, there may not be a nailed down definition of “clean” or healthy” eating. However, it gets you in a “range of uncertainty” Is McDonalds clean? No. Is Pizza clean? Nope. Is brown rice clean? Maybe. I should ask what they mean by their usage of clean. Have I made my point a little bitter? I view usage of vague terms like that not as useless, but as “gets you close to the target without getting lost in the weeds.” Hope this helps.
