In a brief moment of common courtesy and intellectual open-mindedness, Cameron once agreed to debate global-warming skeptics, including another filmmaker named Ann McElhinney.
Cameron soon started demanding various changes to the terms — that it be switched from a debate to a roundtable discussion, that only Cameron be allowed to film it, that all media be kept out, etc.
McElhinney’s group accepted all the changes. But literally a day before the debate, Cameron cancelled. So much for wanting a shoot-out at high noon.
