The thing foe me was that I felt by voting I was giving legitimacy to the system and in some way (even minimally) playing a part in its oppression and abuse. I want people to see that voting is not the only way to achieve change, and that "direct action gets the goods."
On top of this I feel by voting "left" no matter what just as harm reduction, you are teaching politicians that that is enough to earn a vote. That as long as they maintain being marginally better than the opposition, it doesnt matter what they do. They can depend on your vote cause at least they arent the other guy. I view voting left no matter what is exactly what has gotten us into this mess, not as a way to fight it. I do not view voting as harm reduction, as voting has not stopped fascism in the past, and it will not now.
I vote on individual issues, and if there is a good enough candidate I will vote in local elections. Otherwise I do not vote.
