And I myself am sickened by the constant accusations of being un-American or anti-American if one strongly disagrees with Bush and his policies and/or actions. Those accusations themselves are un-American.
Peter used this quote before, but here's a quote from a past president that I think hit's the nail right on the head:
"The President is merely the most important among a large number of public servants. He should be supported or opposed exactly to the degree which is warranted by his good conduct or bad conduct, his efficiency or inefficiency in rendering loyal, able, and disinterested service to the Nation as a whole. Therefore it is absolutely necessary that there should be full liberty to tell the truth about his acts, and this means that it is exactly necessary to blame him when he does wrong as to praise him when he does right. Any other attitude in an American citizen is both base and servile. To announce that there must be no criticism of the President, or that we are to stand by the President, right or wrong, is not only unpatriotic and servile, but is morally treasonable to the American public. Nothing but the truth should be spoken about him or any one else. But it is even more important to tell the truth, pleasant or unpleasant, about him than about any one else." - Theodore Roosevelt
Our President clearly is not interested in full disclosure of the facts regarding his actions, and in his speeches and the way his administration presents itself there is a strong running theme that criticism of the President is bad for the country, regardless of his actions. This is the attitude I find most anti-American.
