I'm back, after putting the book aside for a month. Anyway, the morality chapter didn't impress me, though I agree with its main conclusions. And I did like Steven Weinberg's quote at the start of the chapter.
Dennett didn't address some of the issues that I thought would turn up in this chapter: religion providing guidance about right & wrong, people finding strength & purpose from religion, etc. While Dennett is entitled to discuss whatever he wants, his topic choices threw me off.
I didn't care for his argument on page 295 that
...anybody who professed that a particular point of moral conviction is not discussable, not debatable, not negotiatable, simply because it is the word of God...should be seen to be making it impossible for the rest of us to take their views seriously...
In my mind, all moral beliefs are based on something fundamental that a person believes at a visceral level. For example, I believe the murder is immoral, while a safety net that ensures that everyone's physical needs are met is moral. Since I can't justify those beliefs objectively, why should a theist have to justify their moral beliefs stemming from religion?
