Other statements from the HI campaign said “the most prominent advocates of global warming aren’t scientists. They are murderers, tyrants, and madmen.” Charles Manson, Osama Bin Laden and Fidel Castro served as examples. But under increasing pressure the HI has pulled the plug on the campaign. The Washington Post has a report here.
In a way, the campaign is remarkable for its faulty logic -- in politics you cannot choose your friends, as the saying goes. By the same token, it would be unconvincing to associate climate skepticism with some hate figure (this does not prevent climate activists from pursuing the same strategy).
On the other side of the policy spectrum the UK campaign group 10:10 released a similarly misconceived movie which they retracted immediately afterwards. Andy Revkin has a story here, and the movie can still be watched on You Tube. The 10:10 movie used a different genre than the HI posters. In both cases the PR people probably thought they were doing something 'cutting edge'. In both cases it did not work.
