There is always a leadership. As human being we are social animals and as social animals there is a hierarchy that is established in any endeavor. Anonymous has adopted a symbol (the man with the question mark for a head), a motto (We are Legion etc. etc.) and posts forth goals to be established. While the position may be that these are separate groups just bearing the mantle of Anonymous, those same people are not exclusive of each other. The skill set and culture is a small one that more than likely has various requirements to become part of and so closes itself off from the larger community. This means that the same people are moving in this circle and so there is a leadership structure, even if unofficial.
Anonymous may enjoy hiding behind the name and banner, but there is a leadership structure. Even if the leadership is as informal as a group of friends, there is still someone designing the ideas and establishing the goals and symbols to adopt. Anonymous is honestly not random enough in its selection of targets to reflect a broad spectrum of ideologies and groups. The same people are taking up the mantle of Anonymous even if the exact troops may change.
Their proposed attack on Fox News for calling the protesters names is simply wrong. To deny someone else their freedom of speech just because there is disagreement is not upholding freedom of speech in the slightest. Fox News talk shows have the ability to say as they want, just as we have the right to turn off those channels. So long as they adhere to the ideals of journalism in their actual news casts then they are doing their jobs. Fox News accuses other stations of publishing propaganda just as they accuse Fox of the same. Fox News points out poor journalism and false reports just as others point out the mistakes of Fox. Both sides go at each other.
The Occupy Wallstreet Protesters should denounce the activities of this group performed on their behalf. Anonymous is only going to serve to bring more attention to the words of Fox, give them validity in the eyes of the public and possibly turn opinion against the Occupy Wallstreet movement.
