Very often people object that nonviolence seems to imply passive acceptance of injustice and evil and therefore that it is a kind of cooperation with evil. Not at all. The genuine concept of nonviolence implies not only active and effective resistance to evil but in fact a more effective resistance… But the resistance which is taught in the Gospel is aimed not at the evil-doer but at evil in its source.

from Passion For Peace
