No, I will just have to remember that, in certain places that are new to me, if I can't appeal to someone's better nature that's a reflection of them and not my problem
You will presumably still have to prepare yourself for seeing the phrase used in a context that means something different to someone else. And to be honest, although someone can empathise with someone else's feelings/perspective/understanding about a phrase, I do not think that means that it must become a "phrase non grata" on any thread or forum! I do not think that is to do with "better nature", it is just a fact that the phrase means different things to different people in different contexts and may be the phrase that they need to use to express their experience/perspective/feelings on a thread., without meaning to upset anyone and without knowing about the "No Contact" context that you described. The very nature of the title of this thread created this discussion. No explanation was given regarding "No Contact" as opposed to "no contact".
Anyway, hope you don't find its use by others who have no idea of the difference , who need to use that phrase in their own context in their own way, too upsetting.
