Although the notion has been around ever since the country's founding, the word "treason" is increasingly being applied to opponents of the current administration's policies and the ideology of its supporters. The 9-11 attacks and the assumption of power by a Republican majority since 2000 have dramatically increased the trend whereby those who disagree with the ruling regime's ideas and actions are being labeled as traitors to the country.
Below I have included links to a snapshot of issues and persons that illustrate this trend. In some cases, the links depict a summary of right wing commentary and accusations, and in some cases, the right wing sources are clearly peripheral. In addition, it must be admitted that some opponents of the Bush administration have themselves referred to the president and his actions as traitorous. So it's important to acknowledge the necessary qualifications. At the same time, the growing frequency and intensity of the accusations of "treason" from the right represents a great cause for concern.
Below are some of the names of those accusing the "left" of treason and those being accused, which I have indicated following the link:
Michael Moore accused
Ann Coulter accuser
Eason and CNN accused
Ward Churchill accused
John Kerry accused
NY Sun - War Protestors accuser and accused
Southern Reconstructionists accuser
The UN accused
Zell Miller accuser
Washington Times and Marvin Olasky accusers
Powerline and President Carter accuser and accused
As I said, this represents the product of only a quick google search. Maybe someone with more time and better expertise could do a more detailed and thorough investigation. But I think it's enough to show the degree to which the charge is being made against opponents of Bush and the conservative establishment.
Fascism in Nazi Germany was above all else, a hyper-violent strain of nationalism, which in addition to its goals of world domination, violently oppressed its opponents at home. Is it looking familiar here? Welcome to the new Conservative Political Correctness.
