When you are dealing with a mass movement, as opposed to a quote-unquote "elite," you are talking to people who don't have time to read long research papers. You have to communicate with them in sound bites, around every other thing they are doing. So it takes a long time to shift people from one message to the next, especially if your foundational narrative was, "The only one thing in the entire world you should be paying attention to is Darfur."
