Voter apathy is a difficult thing to understand, especially since so many people fought so hard to make it possible. This is especially true when it comes to women. While some ancient civilizations allowed women to vote, it is a relatively recent phenomenon in our Western civilization.
New Zealand was the first modern country to give women the right to vote- in 1893. In Canada women could vote in some provincial elections as early as 1916 but only won the right to vote federally in 1919. In the US the national right came in 1920.
Humour was a tool the Canadian suffragettes used. Led by Nellie McClung they held a Mock Parliament in Manitoba in 1914. The main topic under discussion was 'Should men have the right to vote?', with arguments such as "Oh no, man is made for something higher and better than voting...Politics unsettles men, and unsettled men mean unsettled bills, broken furniture, broken vows, and divorce!" The Parliament was a great success and women could vote in Manitoba two years later.
That wasn't the end of the road for women's rights, though. Women in Canada were still not considered "persons" according to the British North America Act with the right to occupy a seat in the Senate, a decision upheld by the Supreme court in 1928. A group of suffragettes from Alberta known as the Famous Five(Emily Murphy, Irene Parlby, Nellie McClung, Louise McKinney and Henrietta Edwards)worked tirelessly towards gaining this right, even though a woman had already been elected to the House of Commons. It wasn't that a senate seat was a bigger prize (it wasn't) but the idea of being excluded from being classified as "persons" was what prodded them on. The "persons case" as it came to be called was overturned by the Privy council the next year.
Considering the time, effort and sacrifices of all those who have worked to give us the right to vote, casting our ballot seems to me to be not just a right, but an obligation.
