It's not so much the question in this instance, I mean, who really gives a shit! It's the principle that a supposedly anonymous vote, whether it be for a sideshow like SSM, or a vote where you reveal your political preferences, is anything but anonymous. Your answer is linked with YOU, in a government database, and if you're happy that your response to whatever vote you cast in this manner, will never be used against you, and I mean NEVER, by a government, or agency, present or future, then I'm happy for you. Ignorance is bliss, a luxury to enjoy. Note - I'm NOT saying you're ignorant, rather a very trusting soul who has faith in your government to always look after your interests.
