I do believe that nice religious people make the world safe for extremists by teaching us [...] that faith is a virtue, teaching us that there's something good about holding beliefs without any substantiating evidence. Once you buy into that, [...] then the door is opened to extremists who defend their extremism by saying, 'Oh well, it's my faith, you can't touch it, you can't criticise my faith, I don't even need to defend it because faith is faith.'
