You're describing what used to be recognized as "obreption" and "subreption", two crimes under American Common Law. The terms come from the Latin "reptis" (as in "reptile") and refer to crawling towards one thing, or away from another. The crimes have to do with gradual, deliberate efforts to migrate away from the tenets of an established government, and toward another, not-yet-established political system, through the use of social networking. When deliberate, this is likely a form of treason. It's interesting that today most people are unaware of these crimes - only a few historians, and the Vatican, seem to remember them as crimes. The Vatican certainly ought to; it was how they made their initial inroads into the pagan communities when they spread across medieval Europe popping up Gothic cathedrals like McDonald's franchises.
Anonymous is a less mature, less cohesive, less dangerous version.
What makes Anonymous dangerous - and I hesitate to use those two words together, because many of them would take it as an ego-boost - is the ignorance of much of the public. When most people today don't have an understanding of the rights and values that founded the Union, let alone how they work, a group of script kiddies with a quasi-anarchic approach is going to seem like a valid thing to join up with. It even has an air of mystique to it, combined with a heady rush that comes with convincing people that they're "doing something meaningful" and "smashing the system".
News flash: Twelve years of Bush smashed our system. Reagonomics smashed our system. The Kennedy assassination really smashed our system. Want to "do something meaningful"? Make it work again. Learn your rights and how the law actually works, not what the status quo has tried to tell you. Assert your rights, and those of others, using the very structure that was built and put into place to uphold those rights. Gather others together with healthy, unifying philosophies that they can all buy into and support, and which lead to upholding a structure of law and rights that a country needs to have in order to function. The current basis of the system doesn't work for you? Gather people together and patch the system - but make sure you know you and others know what you're doing, and why you're doing it. Make sure your revisions are well-documented so that others may clearly understand them. This is basic coding standards, applied to revising our system. Because to be honest, if the system were code-based, Anonymous would be less a group of script kiddies and more a loose collection of people releasing borked code and malware, and calling it good.
