I need to update that (thanks for pointing it out).
This is actually our new logo.
We toyed around with the idea of having a different "non Anonymous" logo as some people suggested it scared away people sometimes. But to my surprise, more people missed the old logo and actually preferred it.
Anonymous is an idea. It's different for everyone. In that idea, people do unify into groups (mostly only temporarily, but sometimes long term).
For me and those who I normally associate with as Anonymous.... We seek to right some wrongs, give everyone a voice, and generally make people aware of what is going on around them (you'd be surprised on how many people don't know what's going on in the world).
I believe the system is broken and we really can not fix the system using the system. And I believe more people need to understand that. Can you fix something using the very thing which is broken, to fix it's self?
And when those behind the system are unwilling to change the system, which is against you, do you really expect them to help you take them on? To put that another way..... Would you help someone to fight you?
That's one of many ideological concepts. You'd have to pick one for me to narrow it down.
