Most of the posting on this site is by far certainly positive and blue sky in nature. So, I ask: if everyone is so secure in the DD, why the close mindedness to the consideration of other possibilities? If you find my posts consistently the same, I could say that about the rest of the posts and posters 100 to 1 of mine and probably more. This should bring about some thinking, however I don't expect that to happen given the sentiment here. I post contrarian as a way of receiving meaningful and thoughtful response so as to gain further perspective and debate. In some cases I have received some very nice and thoughtful responses and ones without the barbs or accusations. The latter come from open and intelligent people. The others come from the unconscious.
