1. Claiming to be an idea instead of an group/organization) How can someone be an idea?
support an idea, join, don't support it anymore? leave, idea's can change, multiple ideas happen at the same time, join the ones you approve of.
2. Claiming to have no leader(ship)) Umm... Anonymous must have a leadership. Someone started the whole Anonymous-thing. Anons claim to have no leader? Strange, so Anonymous is a chaotic, corrupted hackergroup with no rules and boundaries? Then how are they able to work together like a fine oiled machine? There is someone pulling the ropes.
there is no leader. you can be anonymous, I can be anonymous, everyone can be anonymous. That's the strenght. No one is a real leader, someone can lead by saying "hey let's do this" and then the rest are like, yeah let's do that or are like, nahh it's boring. if the "hey let's do this" is a good idea according to multiple "members" (you cannot be a real member of something that doesn't actually exist) the idea can be executed. so there is no leader. you can tell anonymous to do something and it will be just as real as when I tell it or someone famous within anonymous tells them.
so yeah, basically, anonymous are a lot of different groups with different people and it's really chaotic, there are no rules and no boundaries.
One part of the group might try to help the freedom fighters in Syria, the other part might help the government.
It's a great way to show that it's actually possible to have a group working together, of people from different country's, races, religions and cultures. they work together one day, to try to accomplish a goal, and work against each other the other day, because they have a different idea about another subject. it works, that part is proven, but it's still a chaos, they are not all sharing the same ideas, the same ethics and cultures, but they are who they are, they are anonymous. I am anonymous, you are anonymous, everyone who wants to be anonymous is anonymous.
