It gave me a different perspective on things, I'll give it that. Lots of pictures, and it was bigger than I expected, also a good thing, and it included lots of little gems like how to refer to a transgender person, and a list of gay friendly deities. As for the section about blood in Hinduism, I think he may have been confused with Islam.
I would not however recommend this book to anyone who is already practising a religion or tradition, but to someone who is thinking about converting or who wants to know more about the spirituality of their friends.
For me however this book had little use.
