"..the Unabomber gets remembered as this struggle's John Brown, not this struggle's Abraham Lincoln."

You could be right about this. But then you could be wrong. Ideas still matter, and their particular expression still can have material impacts. Time will tell. Will Kaczynski's work inspire the sort of material, decisive impact that Martin Luther's works inspired during the Reformation's wars?? or Will Kaczynski as you say be more like John brown, while the real decisive impact will be made by those that actually organize and lead. (Just staying with your analogy). Only time will tell.
