Admittedly, I have given a NO to a number of comments which I thought were NOT helpful, but only on one occasion, that I can recall, have I said a reply was uncivil.  It is of course only an opinion, my opinion, when I state that a reply is not a good reply.  Sometimes I am amiss  and do not  know what is going on both post and the reply. We are expressing a personal value and a judgement.  I do support the endeavor to keep the comment section 'civil'.  What is dismaying is judgment rendered by whomevers to posters for tendering an opinion on the worth of a post...even to posts that have no interest to them and to which they give only a cursory glimpse.  What is happening;  after posting a reply one must wander through a mine field of three posts that usually have no meaning to us, and we are held accountable solely for what we think about them, or even not think about them.  It is not 'possible' to get into the mind of the rater, but that is what the 'powers to be'  think they can do.
