It’s not violence, insurrection. It’s not guns and bombs and prison camps and purges. The conventional wisdom is wrong and ahistorical. There is only one defensible means of social change at the general level. That is the use of nonviolent resistance and noncooperation.
For info about nonviolent resistance- the popular seizure of political power through mass democratic action- check out Gene Sharp’s From Dictatorship to Democracy (free PDF, just under 100 pages) and the superb new book by Srdja Popovic, Blueprint for Revolution. I read the latter over the weekend, it’s a quick, funnier, and less technical version of From Dictatorship to Democracy.
