dissident

You do not become a 'dissident' just because you decide one day to take up
this most unusual career. You are thrown into it by your personal sense of
responsibility, combined with a complex set of external circumstances. You
are cast out of the existing structures and placed in a position of conflict
with them. It begins as an attempt to do your work well, and ends with being
branded an enemy of society. [Václav Havel]
