If the message of the protesters was "consumers are the problem with GHG emissions" and they are personally among the worst consumer emitters of GHG's, then I can see an argument for hypocrisy.



However, in general, I don't think this is enough to stunt their message. They may be misguided about some things, but still right about others. Their message is certainly less convincing if they give off the vibe that they're not taking their own advice, sure.

If they're message is, in fact, correct... If there is a monster, and it is being poked... then even if they're hypocrites (like we are all hypocrites), they're still right.

What are you going to do? Ignore what you know is right because you don't like the messenger?
