I do believe that nice religious people make the world safe for extremists by teaching us that faith is a virtue, that there’s something good about holding beliefs without any substantiating evidence, that you believe because you believe. 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.’
