Since the revelation was made that President Bush secretly authorized the National Security Agency to spy on Americans, I've heard some frightening excuses given as to why this was ok. Granted, some of it is as moronic as the caller on C-Span the other morning saying, "I 'ain't got nothin' to hide, so I don't care if they listen in on my phone calls." This type of stupidity is obviously a product of inbreeding, so there isn't much that can be done to combat this.
Then, there are the Bush apologists, driven by ideological purity, which says that all is fair in the "war on terrah'"; once again, I don't know how to counteract drinking the Kool-aid. There's not much that one can come up with that will sway a dyed-in-the-wool conservative, from their preconceived notions.
What concerns me is the general level of malaise and apparent lack of perspective of many other Americans about this, however.
Michael Hawkins, over at Spontaneous Arising, has some of the best (and genuinely frightening) analysis on what all of this means. I was fascinated by his using Benthem's panopticon in illustrating the scope and possibilities of surveillance possible, given our enhanced technological capabilities.
This stuff is worth reading, if you can wedge it in amongst the gift wrapping, eggnog and fruitcake of the season.
