This has been the most effective form of climate protest by far. When they block oil terminals or spray paint car dealerships no one will cover it making the protest pretty much useless, like a guy set himself on fire to protest climate change and that was barely covered. The stuff they do doesn’t actually cause any damage but the media actually covers it because they can spin it as rage bait against the protestors but at least it gets coverage.
