You see it in forms both subtle and pervasive. Republicans and their lock-step supporters within certain law enforcement agencies, treating dissidents as insurgents. Organizations that pose a threat to the status quo, are targeted and any means necessary are used to marginalize and weaken them.
What we have seen as conservative attitudes have become ever more strident, is systematic infiltration of organizations that conservatives find threatening, whether they are gun-control advocates, vegetarians, peace activists or even garden-variety environmentalists. Even forms of civil disobedience are portrayed as "terrorist activities", lumping basic protesting with exploding IED's near an Iraqi eheckpoint. The treatment of protesters in St. Paul Minnesota illustrates the lines of thinking of law enforcement towards those who seek to express their point of views through protest.
The Cheney pre-emption doctrine has now been applied to American citizens. Police raids of houses that contain people who disagree with Republicans in St. Paul illustrates how close we have become to a police state. Where the government can conduct surveillance on us, without reasonable oversight, the very mechanisms that Nixon wanted to utilize with his plumbers are surpassed with speed and zeal. Where law enforcement and conservative activists purposely infiltrate groups they are threatened by, you get a sense of just how radical and totalitarian the movement has become.
It just seems in looking at the big picture, that with so many conservatives viewing politics through the lense of manichaean absolutism, that any means must be deployed to prevent undesirable ends. Armageddon is imminent, and all must take up arms in whatever way possible, to ensure this nation sides with Jesus. All I can say is, I'm glad the Republicans didn't hold their convention here. For all I know, I would have needed a new door.
