Anarchy is just conformism on its head, it is something against the government, yet they have no considerations for what is after government - they are just anti.
Rebellion is something far more beautiful, it is the intent to cause real change, a positive movement. It is not against, it simply wants to improve something. All the religious founders have been rebellious in their way, but usually a revolution comes about after they die, now there is organized rebellion and it becomes just another tradition. It is now a dead thing, but still people cling.
I am pleased that things like Occupy Place are happening for this reason, it is perhaps too much a revolution but at least it is founded in meditation, it is a very positive thing. Anarchy is something different, it is just a destruction of civilization, but it wants nothing on the other side.
