Indeed, D, I do think this is very powerful literature, and it once again reminds me of the introduction where they speak about how genre works are often tossed aside as "lesser" works.
I think the same can be said with film, music, video games, anything really. There is depth, quality and importance to be found in all different areas, and limiting one's self doesn't make a whole lot of sense.
What you wrote in your post above is exactly how I feel about religion/spirituality. I consider myself a very deeply spiritual person, but I just haven't found a religion which I felt suited my own beliefs and way of looking at things.
And when I say that I "don't believe in God" or whatnot, it's simply that I do not believe in the whole "big, vengeful man with a white beard, sitting in the clouds and showering plagues upon his people" way of looking at it. I honestly don't know where my belief lies with the idea of a "creator(s)".
I think it's very sad that there are such horrible things done in the name of religion, especially when the victims and perpetrators of these acts are so, so close in their beliefs. You look at the teachings of Islam and the teachings of Judaism, and they're almost identical - especially in, as you said, their encouragement of love, acceptance and peace.
So, in the end, I think you and I really are in the same page with our beliefs - the only difference being that you attribute an actual religion to yours, whereas I am more of a mix-and-match
