I expected this book to be more hard-hitting than it was. As someone who spent decades involved in apologetics, I thought maybe he'd use some logic or reason in his arguments, but his entire argument was simply an appeal to emotions and passions. Sure, there were some good parts of the book that really made me reflect and his intentions were honourable. If the book had simply been his personal journey, then that would be fine. Such a thing is subjective and personal and you can't say much about it, but instead he tries to make arguments from the Bible, philosophy, theology and anthropology about why Christians should convert to his view-point. I found his arguments to be weak, and he had to go through much unconvincing exegetical gymnastics to try and read into the Bible what he wanted it to say, forgetting that Christianity, especially Roman Catholicism, is based on a lot more than a literal reading of the Bible, aka 2000 years of teaching, preaching, philosophy, writing, living and theology.
I could also write an entire novel about his hypocrisy. He complains that Conservatives and Christians make too much out of the same-sex marriage issue to the exclusion of all else (not true, btw), but then here he is, switching his denomination, his career and writing an entire book about this one issue, in which he even says that this is the single biggest issue the Church is facing today. Go figure. And for all his complaining that Conservatives are "mean", he spends a great deal of time and effort bullying them into believing what he believes, ridiculing them, insulting them, and making many false accusations and blanket statements about them.
I could go on, but I won't. I'd say it's worth a read just to see where's he coming from, because there are a lot of Conservatives out there imputing false or made-up motives to his actions and change of belief.
