I need to gather my notes before I can write a proper review, however, below are some of my off-the-shelf takeaways/critics of the book:
Dawkins is too intimidating in his opinions - he hammers on and hammers on until either you have changed your opinion or you get exhausted. Neither sounds good for someone having a constructive argument.

The crux of the argument is - and this is something that I've wondered for quite some time - keeping aside the hard religious conservatism, why even the so-called liberal values teach us that we should question everything, except when it comes to religion. Religion is somehow the holy grail of the argument (pardon my pun) - you can't just question it, no matter what. That's bewildering, to say the least.

* The problem of "Unquestioned faith is a virtue" and the power of religion to "console" us through the bad times. Believing in God and believing in belief are not the same thing.
