"You have to vote! It doesn't matter who you vote for, just vote!"
Fuck you. Stop saying this. It does matter who you vote for, and if you don't have an informed opinion about it, you should stay out of the game.
If someone hasn't taken the time to become informed, your petulant platitudes are not going to change that. All that you will accomplish is having another uninformed voter making an uninformed decision that will just as likely end up being against their and your best interests.
Corrolary: You should vote "NO" on every Proposition unless you actually know what the fuck you're talking about. The California Proposition system is asinine, and the way to do least harm is to reject by default.
