Nowhere in that does it really explain why voting is counter productive. Voting is a tool, and a very cheap one. It only costs at most an hour once every 3 years and requiring knowledge of current events and politics, which is stuff you will know about anyway if you're involved in any kind of direct action.

The only potential argument there is the psychological one, where people are lead to think voting is enough to do their part, but I don't think that's a strong enough argument to pass up choosing your opposition. As shit as Labour is, National and Act are worse, and by any logic other than accellerationism (which is a terrible idea of you care about the human cost), Labour will make fighting capitalism that little bit easier.

I understand not running for office. That article gives good reasons that actually joining politics is a wasted effort. It takes a lot of time and money, and almost always ends up making people slide towards the "reasonable politician", not the radical that they promised to be.
