It's a way of looking at things I suppose, but it solves nothing, even if the data is correct.
All the people who don't vote, who are entitled to vote, all have their own reasons for not voting. If you want to call it apathy, then perhaps there should be an 'Apathy' Party formed?
None of the above (for me anyway) excuses the deliberate spoiling of an official ballot paper, it is an insult to those who's name is on the paper, it is an insult to those who fought for years to get the vote, it is an insult to those who have to sit in the polling stations all day and to those who count the vote, who work into the wee hours, to deliver a result.
I would sum it up with the words of a friend of mine years ago who regularly helped to count the votes in many elections she said " whenever I come across a spoiled ballot I feel like I could slap the face of the person who did it, it's like they are little kids who crying and stamping their feet because they want something that's not on offer"
