I've held the belief that if a someone can't recognize and clearly identify the differences between criticism based on merits and criticism based on bias, then there is no point attempting to do "what they want," because they don't know how to identify what they want even if they got it.
As they accomplish their goals the moderate extreme membership drops out and the median voice moves ever towards the radical. "You either die a hero or live long enough to see yourself become a villain" sort of thing. I'm not trying to say that about any specific movement, but it does seem like the "hero" aspect of many movements is on the decline.
