Change from inside has a very poor track record. People who say that are usually rationalizing their involvement. Even non-violent protests are adversarial. The history of the world seems to suggest that is the one tried and known method for change is adversarial confrontation. If you look at it from a game theory/economics point of view, there is little incentive for people to change unless you change the landscape and the factors that compel their behavior. Change from inside really doesn't have that because organizations/organisms/nature are resistant to change -- if it is working why risk it? Very few organizations have the ability to disrupt itself.

Has it? Or is it just less visible because it happens over a decade or two? Germany's left wing and their March Through The Institutions comes to mind as a very successful change from inside.
