It is tempting to wonder if activists sympathetic to climate and evolution denial might be grasping opportunities to discredit science in general by spreading vaccine and HIV denialism.So, having described how these "denialist" movements set themselves up as underdogs fighting a corrupt elite engaged in conspiracy, the author gets a touch of paranoia and conspiracy theory himself. Look out, everyone: denialist movements are all part of a big conspiracy to weaken the public's trust in all-powerful Science! Aiee!
