Please please please correct me if I'm wrong, but nobody can know who you voted for unless you tell them. Just that you voted. Ballots are unsigned and you place it in the box (supervised, but folded and unexamined) yourself.
And please, nobody should be photographing their ballots or even using a phone or camera in the polling station. If it is possible to generate proof of vote, the controlling assholes of the world will use that to illegally coerce votes.
Yes, and not everyone can safely escape such a relationship. Your response comes off as dismissive (I assume unintentionally), but we need to raise awareness and provide support for the shockingly high number of people trapped in relationships like this.
