It's not just Iranians who make that comparison - have you looked into any Christian conspiracy theories lately? Freemasons rule the world, politicians organize Satanic rituals and the queen is a reptile. Most of this is thanks to people being crazy enough to buy into this shit without doing their research.
I find it sad that people can be executed for their beliefs based on religious paranoia - but that's the way things have been going for years. And uninformed people say Satanists are the bad guys?
