The problem is that you think that terrorists/fundamentalists are rational
I don't know how rational (its not a black or white issue) terrorists are anymore than you do. If they were rational as early as 1998 when they were negotiating with American oil companies for a pipeline through Afganistan, then they are capable of being rational now. Perhaps it is the US that was not being rational, we do not know. Western ideals have not had any significant changes in influence in the past 10 years when some of these "terrorist" organizations were allies to the US. The Western world has been spreading its ideals for decades. Therefore, the argument that their motivation for attacking us is based on their violent hatred of western influence, freedom, democracy, capitalism, or decadence is complete hog wash.

About Las Vegas: did you actually go there, or are you just basing your judgement on assumptions, hearsay or media?
I'm basing it on facts. Las Vegas is pure opulence, offering the most extravagant services for those with enough cash to request it. Where else can you chase naked women around with a paint ball gun for $300, order a prostitute via yellow pages while staying at a 5 star hotel, walk down the strip drinking out of a bottle of beer in clear view of smiling law enforcement, and then get married under the authority of a preacher wearing Elvis garb... all in the same day?

Las Vegas is one of the (if not the) fastest growing cities in America because you can do damn near anything you desire without consequences. Not because they have kiddie rides at the amusement park. Las Vegas represents American capitalism, and everything that spawns from it (excess). I challenge anyone to try and paint it as moral community.

p.s. I have two friends who live there, and will be there in two weeks given we are willing to side track the road trip to San Diego for a few days.
