NVC values honestly expressing your own needs and feeling and empathetically listening to those of others.
You know, I'm generally considered to be reasonably skilled at communications; and I think that I have had some success in remaining cordial and attentive to both my colleagues and the members of the community I often interact with.
To be honest, if someone were to address me in the way you describe in your examples, I would almost certainly be seriously offended. You call this Non-Violent Communication, but I find it both condescending and dismissive, and would certainly perceive it as a deliberate attempt at being passive-aggressive.
TL;DR: YVVM. Not all methods of communication are appropriate for all media, or of all audiences.
I'm sorry if I offended you. That was not my intent. I was only trying to help us all communicate and get along better.
Thank you, Derric Atzrott
