In other words, the innocent people are also guilty because by voting they agree to accept the decisions their appointed leaders take for them.
I don't agree. I reject every version of this argument. Specifically, I reject:
1) If you don't vote, you have no right to complain if leaders do bad things. You had a chance and you gave it up.
2) If you vote and the leaders you choose win, you have no right to complain if they do bad things. You got what you asked for.
3) If you vote and the leaders you choose lose, you have no right to complain if those who won do bad things. You lost fair and square.
4) If you don't vote, you are responsible for what your government does. You could have acted to stop it and failed to act.
5) If you vote and the leaders you choose win, you are responsible for what they do. You put them in power.
You can vote in self-defense or for the lesser of two evils without becoming responsible for the evils elected leaders do.
