Our strength (used to be) in our unity, not our diversity. I fear Roberts is right. I believe the world is on the brink of some very scary times. Political Correcness has already done a pretty good job of destroying the West.
That's blaming democracy for the actions of voters.
This is meant to represent the concept that great strength comes from many bound together in a single purpose. Where one would be too weak, all together are capable.
And diversity is the antithesis of working together for one unified goal. The various groups' lack of any agreed upon culture or standards other than a shared marketplace means that the government must regulate ever more elements, and must enforce those laws and rules. The governed no longer agree sufficiently for the phrase "consent of the governed" to have meaning. And thus we may be destined to descend into empire, and thence into tyranny.
Further, an outside force may enjoy the aid of a fifth column already in place within the US. We see at least the suspicion of such a possibility with moslems in the post 911 world. This too weakens us - especially if we face an enemy with a large domestic constituency.
This is exactly why I favor electing 'sons of the rich' like our current President, as opposed to the 'self-made' politician, of which Clintoon stands as the most infamous example. Bush is much like a hereditary ruler in that he benefits from 'insider' knowledge of world affairs, and his business/social relationships impress upon him a profound respect for the forces and families who made and hold this country together. BC, by contrast, wanted to 'reinvent' government, and his ilk always want to plow up the social fabric, keep things in turmoil, which keeps them afloat politically. Always in need of money, they are more open to corruption.
As long as Americans have the good sense to elect enough aristocrats to high office, we will pull through. If demogogues grab power, they will promote their various 'cultural revolutions', always finding grievous fault with the existing order, and promising a quick solution to the gullible and less-advantaged. They will also be unwilling to take foreign-policy risks, preferring short-term accommodation to long-term security.
...ala the Democratic party. We can't have democracy without the impossible combination of a propaganda ban and an absolute cap on the size of government. If the USSR had elections - Joe Stalin would have had no trouble getting re-elected by the sheeple
