Yes well, as you demonstrate so well, the difference between expressing opinion and caustic passion seems to lie only in who is giving and who is receiving. Which brings up a good point or two. Some of this is inevitable. Humans are emotional creatures. Often -- not always -- the blame lies on both sides. One side dishes out too much and the other side wears its feelings on its sleeves. More frequently still, each side plays both rolls -- arrow thrower and wounded dramatist. (I am not referring to Ivan here.) No one thinks THEY are guilty. Truth be told, we are probably all guilty at some time or another. It is difficult to be perfect in this regard, especially on issues you personally find outrageous. So we just go on, doing the best we can. Hopefully that will be good enough to keep a strong base.
rolls = roles. LOL! I always do that.
