"I never called you un-American."
I never said you did Dr Guy. Although, to be pedantic, I have no quarrel with the label "un-American", as I am Australian, and thus probably by definition unAmerican. But I would not count myself as anti-American, as some others have accused me.
I don't think you can quite accuse my list of the same obsession with contemporaries as the Discovery list. Several members of my list are dead, some for well over a century. But you're right that I haven't delved back several centuries. This is for two reasons really: I am Australian and thus don't have a very extensive knowledge of US history, and 2, people like George Washington are important to Americans because he founded the nation, whereas to me, an Australian, that has much less value. I understand why an American would put him on their list, but for an Australian, I find little reason to admire him. I don't mean that he isn't admirable, just that the reasons for which he is admirable are not particularly important to me.
