„The fact is that climate change, if it were caused by gay sex, or caused by the practice of eating puppies, millions of Americans would right now be massing on the street insisting that the administration do something about it."

I'd wager that the main problem here is that there's no easy target to blaim. We ourselves are to blaim in terms of climate change. We can't protest against our own actions. People need easy targets to protest against.
