I believe it is in the best interest of all of us - you included, Pandora - that we allow for the differences of our opinions, with the caution that in most cases one can support their position with reliable citations, or present them as opinions and not fact.  You took my comment way too defensively, as I was stating a general observation of why many of us used and valued the blocking feature.  You had said it was to avoid dialogue, but I said I saw it as a way to filter out those who bombard us with sarcastic and poorly disguised commentary.  You react as if it was only addressed to you - it was not.  I try pretty hard to "listen" to what you post, now that I cannot block you, and to find the useful content in what you state.  I must say that with you I am yet to have the favor returned.  But we are forced together here, at least for now, so I will make the best of it, in spite of our past war of words.  And I again ask that you think twice about reacting so defensively and so fast.
