It is indeed an idealogy, one as hateful and vitriolic as any except that of the Third Reich. Rather than Mein Kampf, their bible is basically Orwell's 1984: a Big Brother philosophy with every citizen monitored and no appeal from government suppression other than a justice system controlled by the government itself, and a Supreme Leader with all power onto himself.
The Third Reich only lasted 12 years, but that was enough to ruin a once-mighty nation. How far have we fallen under 8 years of Bush & Cheney & Rove? When I was a child the President answered to Congress, the Supreme Court was independent from the White House, even the police wouldn't enter your house without a warrant (which was difficult to get) and anyone declaring that the president should have the right to summarily declare any citizen a terrorist and whisk them off to prisons without charge and without access to a lawyer, would have been labeled a communist and laughed at in derision.
Today the man who is president because of a stolen election does all those things with impunity. We have lost the 500-year-old right of Habeus Corpus. The Republican elite rape the treasury for their personal gain. We have become a nation that invades the weak and tortures the helpless. We are despised by decent people throughout the world.
Enough is enough. This idealogy has to be more than discredited. It must be soundly resisted, defeated, dismantled, and thrown on the dust-heap of History, like fascism and National Socialism before it.
