A lot of "green" policies are holier than thou people trying to impose their lifestyle preferences in ways that don't actually help. Good examples are the anti-nuclear power movement and the nonsense that is plastic "recycling".
Also "new urbanism" that's just people who want more bike(-only) paths for recreation. Yes, there is such a thing as better urban design that reduces car dependency. There are real bike commuters. I totally respect and tangibly support both, due to environmental and other concerns. But I'm not interested in hearing from people who oppose mass transit, abuse pedestrians, and regularly drive their bikes (as aggressively as they ride) to the rally point for their recreational large-group rides. That's not advocacy for anything but oneself.
