Why "get angry" just because someone gives SOME credit to Gene Sharp for the fact that his IDEAS had some influence - which is not to claim that they were decisive. People who put their lives on the line do so for a variety of reasons and in a variety of ways and they may draw on a variety of sources for ideas - including how to function most effectively in such a situation based on historical precedents. It seems that some of the people involved in the revolution in Egypt, especially those who seem to have played an important organisational role, clearly did draw on his ideas and valued them:

When the nonpartisan International Center on Nonviolent Conflict, which trains democracy activists, slipped into Cairo several years ago to conduct a workshop, among the papers it distributed was Mr. Sharp's "198 Methods of Nonviolent Action,"a list of tactics that range from hunger strikes to "protest disrobing" to "disclosing identities of secret agents."

Dalia Ziada, an Egyptian blogger and activist who attended the workshop and later organized similar sessions on her own, said trainees were active in both the Tunisia and Egypt revolts. She said that some activists translated excerpts of Mr. Sharp's work into Arabic, and that his message of "attacking weaknesses of dictators" stuck with them.

Maybe it's because I'm a Londoner - that I moved to Nice.
