Thank you all
Just wanted to say that I am amazed at the thought and energy put into the discussions here. There are a lot of bright people posting, and their views (even the looney ones - and I'm sure half of the board includes the other half in that category at some time or other) help in understanding a complex situation. It seems that some people will never change their views no matter what is presented to them, but I think most of the people here have had their minds expanded to some degree at least. I know I have.
Thank you all!
