It seems strange to me that someone who (apparently) has just one daughter, who he admits he saw infrequently should be writing about how to bring up children!! In those first few years of life a child's mind is a sponge, absorbing so much it is impossible to stop them falling prey to unhealthy doctrines - was he hoping to isolate her on a desert island? Rather than write her a tenth birthday letter, that it seems she didn't even get until she was eighteen, why didn't he try to be a proper dad and be there to explain and guide her as these things came up? Mind you looking at his comments on tradition and authority perhaps it was a blessing in disguise!
Just like the religious fanatics that he is (rightly) condemning he is confusing art and science, many of the traditional stories of the Bible and other religious works are simply that, artistic, descriptive stories to embellish a point, whether the story is 100% true or not is not important it's the moral code, the message that is important. There are many true records in the Bible (certainly as true as time and translations can possibly allow) but after thousands of years these stories and the example of Jesus' life (regardless of the details of whether Mary rose into Heaven or not) are still a solid foundation for modern life. If you read them with an open mind it is easy to relate them to the world today - fundamental truths that have withstood the passage of time.
I have worked with many scientists over the years, and met many at the leading edge in genome studies, particle physics and astrophysics, many of them are committed Christians, because they understand the limit of human knowledge, that regardless of their next great breakthrough there are many things that we will never understand - controlled by a far greater power whatever you might call him/her. they seem to grasp the difference between fact, belief and faith and the place each has in their lives.
For many Christians the divisions that once tore them apart are becoming less important, like all parts of society there will always be those that seek to exploit differences for their own benefit and power - religion is no different - we all get to hear about the leaders and the extremists, for the real truth listen to the ordinary man/woman and you'll understand what faith is and how it can transform your life.
I'm sorry Mr Dawkins you have a lot to learn about life.
