i think that the issue is very rarely/never individuals (despite hollywood), but the people who allow individuals to go nuts.
to me this is one of the basics of anarchist thought.
people who stand out can do so because of the people who allow them to; culture determines (to some extent, anyway) who and how people will be/choose to be significant.
i'm sure there's a more elegant way to put that.
edit: also, yea, direct action.
