I worry about the need or effectiveness of violent climate action too:

Our demands are – and have to be – more complex than any that have gone before. While I believe that taking out pipelines, refineries, abattoirs, coal plants and SUVs is morally justified, do we really imagine we can bring down the Earth-eating machine this way? Can we really hope that government, industry, oligarchs and those they employ or influence will conclude, “Because we cannot tolerate the sabotage, we will surrender the economic system?” If you are holding a virtual gun to someone’s head, you need to know exactly what you are demanding and whether they can deliver it.
