Is Amazon fore-ordained??

I had no idea that the Amazon review pages were such a hotbed of theological debate!
I recently went looking for 'Greg Boyd' to remember the name of a book I had read and there were 44 customer reviews of his book God of the Possible - 44!. They were about the book but seemed more about either attacking or justifying the theology and Greg Boyd himself (mostly attacking it seemed). Some of the more 'religious' in tone comments just made me cringe.
Why are people so worried by new ideas? Do they think God doesn't want us to think? Greg Boyd is quite clearly a believing Christian genuinely exploring ideas from Scripture. I'm happy to explore alongside.
I find the whole idea of open theology fascinating and it has a lot of feeling right about it. The idea that the future is more open and less preordained than sometimes we've been taught brings a whole host of different responsiblities to us. We do matter, we can make a difference. Is it less 'safe'? Yes, but then we don't worship a tame lion do we?
Thankfully there were some rational and even amusing comments as well. I especially liked this tongue in cheek one "I'm not sure why hyper-Calvinists waste their time reviewing books like these since what man thinks/decides/etc. is all foreordained by God. Therefore, Boyd couldn't help but write this book. So, they should just relax and assume Boyd is a "vessle of wrath."
