The only way to do anything significant about climate change is to convince tens of millions of more people -- at minimum -- to take it as seriously as we do. However angry you get, every solution involves starting with this. So the number one most relevant question is "will this convince people to listen to me, or will it cause them to tune out?"

Are you serious enough to do stuff that will actually move people in the right direction on the issue, even if in your heart of hearts you want to scream in their faces that they aren't moving fast enough? Or are you content to fail so long as you get to yell whatever you want?
