A reported 100,000 people protested in Berlin yesterday. If you’re going to do it, that’s the scale that matters. At that scale, even the happy pacifists can make an impression.
But if you’re just a little warband of 15 people, you better be burning cars for it to get attention. Otherwise, just go plant some trees.
In fact, why isn’t there monthly tree-planting marches. Tear up cement and plant trees where they’re not supposed to be. That’s demonstrating.
