Christians don't believe there's objective morality.

[System of Solace]

Oh wait, I forgot.... it was written by a patriarchal people who imagined this god thing by putting in him a few characteristics of other previous gods that they had heard about.

Whatever is in that book, is just the ramblings of these people and should account for nothing in our society which is very very different from theirs, don't you agree?
Why then are so many people from this society so hung up on this book?

I can't imagine how strange this book will look to people who will live 500 years from now! Perhaps as strange as the Egyptian book of the dead... and as non-representative of reality.

I would bet that has been said many times through the last 2000 years, what do you think.

It means more now. In the past, you could be killed for heresy. Now, there are counties that are not even 20% theist.
