Ah -- then perhaps we didn't communicate clearly to you that the issue we're discussing is not "calling it the Big Bang Theory" but instead "insisting it always be referred to exclusively as 'The Big Bang Theory'".
So maybe we don't disagree at all, and somehow didn't clearly explain what our objections to his behavior were.
I think the conversation turned to a general discussion on calling it "the Big Bang Theory" because the claim that he "insisted it always be referred to exclusively as..." was an assertion made by The New York Times -- an indisputably biased source with a sorry track record where the truth is concerned -- with the specific intent of making a "Bush appointee" look silly, by extension making the President look silly.
Of course I don't believe people should have to walk around qualifying any discussion on the Big Bang with the word "theory". But, I do believe that schools and other public institutions should refrain from endorsing it, or any other theory on the origins of the universe.
