Thanks for reply. The important thing is 'constructive dialogue'...not name calling and rhetorical tricks...in trying to get at a deeper level of understanding....humor can be ok...everyone seems to need help in understanding

There is a debate on National Public Radio website, "Global warming is not a crisis"...that shows that even with leading professors on a vital issue, they have a very difficult time staying honest and constructive in a debate.

best regards
