I won’t tell you how to vote. I just encourage you to vote. You’re not radical for ditching the only miniscule right the state has granted you to do some small aid for your neighbors.
It certainly mattered to Canadian politics. One of our politicians participated in a shoe throwing event at -24 in Montreal where ppl threw their shoes at a picture of Bush to protest US involvement in that incident and Harper 's willingness to engage Canada in a meaningless war. One of the protesters was a provincial left-leaning party co-leader and MNA (Amir Khadir).
However, voting matters more than one successful protest on one issue. You would need to throw thousands of shoes to get shit done if that's how you want to go about it.
