I’ve been meaning to read this for a long time, as it often gets referred to in discourse about religion and belief. I don’t have any particular insight to share, but if I had to sum this up I would say that Dawkins has done the research to back up his arguments, but does come across as a bit ‘all religious people are wrong and foolish’, which I think is a bit harsh (regardless of whether there is a god, lots of people do gain life satisfaction from their faith, and the majority do so without impinging on atheists or agnostics).
