Tankies are really showing their privilege. They aren't under seige so they can afford to wait and keep their self perceived purity. Harm minimization isn't ideal, but does help more than getting out of the way for fascism.
There are more than just presidential elections, and those often matter more, yet they still discourage people from showing up. Then they wonder why candidates they like stay on the fringe.
Voting isn't everything, but it does matter.
