You always have a responsibility to vote! Even here in Canada prominent community leaders take your attitude and it is sad.

Not voting is called voter apathy and says I'm happy with the status quo. You have a responsibility to spoil your vote.

In apartheid South Africa where the election districts were rigged whites were told by the passive liberal educators to spoil there vote as a form of protest. It wasn't untilled the apartheid government had overwhelming spoil voters did they hold a referendum, to compromise on principles and negotiate with terrorists.
