The fact that you would label biblical texts as "evil documents" tells me you've never so much as read one. What is so evil about them? If you'd read any literature of the early to mid-twentieth century, you'd see a lot more evil in those books.
The Christian Bible? Is filled with
stories and
history. The Qu'ran? Poetry and art. I have only come across mentions of evil in these, all of which essentially equate to, "We think this is evil. You shouldn't be evil. So if you believe it too, maybe you shouldn't be doing this."
And if you start going on about what it says are sins, you have to understand that a lot of what they say are sins are more like..."pet peeves the writer had", aside from murder and adultery and stuff. Homosexuality is only mentioned in Leviticus, for example, along with "fabrics woven of two material" (like courderoy) and shaving.
And yes, I have taken certain beliefs about reality from the books I listed. Even Dr. Seuss. For example, I take a few of my beliefs from "
Oh, the Places You'll Go!", among them: The Waiting Place (which I view as sort of the place we go when we dream or are in a coma/vegetative state)(see also the play "Our Town"). If you read anything with an open mind, you will find the answers to some question you have.
And frankly, your view of religion is horrifically offensive, but if it's what makes you happy, I'm not going to tell you it's wrong. But I do wonder what you will do when faced with religious patients or family members of patients who ask you to please pray with them for their loved one. It does happen.
Yes, religion sometimes keeps science from progressing too far. But it also can be helpful. People moan and whine about not being allowed to use stem cells, since certain religions view the practice of harvesting stem cells as similar to murder or abortion. However, this also reveals an enormous opportunistic gap: where else can we get stem cells? Can we find a way to manufacture them? There has been some success turning regular cells into stem cells (though not much), and if there is a breakthrough, there will never be a shortage for study and possibly eventual medical use. No one would bother to look if certain people weren't against it.
My parents taught me to believe what I wanted to believe, but they also told me that my beliefs have no greater value than anyone else's. I think it's true. My beliefs are no more 'correct' than a Muslim, a Christian, or even your mighty beliefs. The same is true in reverse.
So if you want to keep believing all you believe about religion, you go ahead. They're your beliefs, and there's no grand scale of "correctness" against which I could possibly judge them. Maybe, though, you should realize that disrespecting a fundamental part of someone's upbringing and beliefs isn't going to serve you well, since it's going to limit the amount of trust they put in you.
But again, believe what you want to believe.
