I've never really read any of Robert Spencer's books, but saw his documentary named "Islam: What the west needs to know"
This documentary was actually crucial in my decision to leave Islam, but it had a lot to do with timing and my state of mind when I watched.
My parents showed it to me after having shown me all of the violent verses from the Qur'an that were presented in the movie. Since I'd already had a chance to see these verses in the holy book myself and tried to defend them as I looked for context, different translations, scholarly explanations, and read tafsirs' take on them, when I saw the movie I could not cry "out of context!" excuses... not even to myself. If such hadn't been the case, I think I would have hated the movie and everyone who made it for manipulating information to show Islam in a bad light.
The problem with Robert Spencer I think is that, like with FFI, a person must have some basic factual information about the problems with Islam before being exposed to his manner of presenting it. Otherwise, the claims he makes seem so unbelievably extreme that a liberal individual (Muslim or not) will likely think that the facts are being exaggerated or cherry-picked with bad intentions and ignore the message altogether. The sad reality is, much cherry picking and exaggeration are required to show the real Islam in a GOOD light.
I had already seen tons of evidence of Islam being wrong before I watched the movie, but I was staying very strongly in denial. I think deeply in my subconscious I thought, so what if it wasn't all good or even the truth... believing in my peaceful version of Islam was not hurting anyone. When I saw this movie though, I couldn't hold up with denial any longer. I knew that the extreme Muslims that they were showing did not represent most or even the majority of Muslims... but I could not deny that these people were simply following what the scriptures told them. And I could not be a part of a religion that could create so much hate and suffering. So it was at that point, with the evidence of the violence in the scriptures and what it could lead to in the real world presented so clearly before me, that my mind was freed from denial.
