Successful movements have understood that it’s absolutely essential not to fall into the trap set out by the authorities and spend one’s time condemning and attempting to police other activists. One makes one’s own principles clear. One expresses what solidarity one can with others who share the same struggle, and if one cannot, tries one’s best to ignore or avoid them, but above all, one keeps the focus on the actual source of violence, without doing or saying anything that might seem to justify that violence because of tactical disagreements you have with fellow activists.
I remember my surprise and amusement, the first time I met activists from the April 6 Youth Movement from Egypt, when the issue of non-violence came up. “Of course we were non-violent,” said one of the original organizers, a young man of liberal politics who actually worked at a bank. “No one ever used firearms, or anything like that. We never did anything more militant than throwing rocks!”
Here was a man who understood what it takes to win a non-violent revolution! He knew that if the police start aiming tear-gas canisters directly at people’s heads, beating them with truncheons, arresting and torturing people, and you have thousands of protesters, then some of them will fight back. There’s no way to absolutely prevent this. The appropriate response is to keep reminding everyone of the violence of the state authorities, and never, ever, start writing long denunciations of fellow activists, claiming they are part of an insane fanatic malevolent cabal…
Gandhi and his movement were regularly denounced in the media, just as non-violent anarchists are also always denounced in the media… as a mere front for more violent, terroristic elements, with whom he was said to be secretly collaborating. He was regularly challenged to prove his non-violent credentials by assisting the authorities in suppressing such elements. Here Gandhi remained resolute. It is always morally superior, he insisted, to oppose injustice through non-violent means than through violent means. However, to oppose injustice through violent means is still morally superior to not doing anything to oppose injustice at all.
And Gandhi was talking about people who were blowing up trains, or assassinating government officials. Not damaging windows or spray-painting rude things about the police.
