I'm all mostly for religious tolerance, and I do believe spirituality has a place in society. However, scripture-based Christianity and scripture-based Islam are both the most pretentious cults that have ever walked the earth, and they deserve every little bit to be scrutinized.
First, I must establish I am NOT bashing Christianity or Islam. I am bashing scripture-based Monotheism, which is an ultra-orthodox interpretation of scripture, the results of which involve theocracies like Saudi Arabia, the Catholic Church and Monarchy a couple hundred years ago, many private schools today, education in Canada less than a 100 years ago, idiocy like your local church, and modern terrorism.
Quite the contrary, the sheer fact alone that most decent people say scripture is "up to interpretation", means most people share a reasonable doubt and questions to the scripture of their religion, and learn more towards the spirituality than the law. (Though most people don't like to admit it, mostly out of pride for their identity...)
The problem with Scripture-Monotheism, is that they assert themselves correct, while condemning the rest of the world to suffering and eternal damnation, and arrogantly believe themselves to understand the creation of life based on faith alone.
Scripture-based Monotheists conveniently assert themselves, so conveniently, that they are the correct religion.
Look, in a world with a cultural and historical diversity as ours, defined by science and logic, you cannot claim that only less than a couple thousand years ago, some prophet was spreading 100% accurate revelations only to the Middle East and North Africa, while completely ignoring the Indigenous peoples of India, Hawaii or Japan, for example.
On that matter, to imply that these indigenous people of India, Hawaii, and Japan are "infidels" for not following the revelations, is to imply that these peoples and their beliefs are somehow of less worth, and I find that incredibly arrogant of Monotheism.
Taking it one step further, if you actually study the history of Judeo-Christianity, you would know that Judaism was originally spread through oral tradition, rather than scripture. Ever play a game of Broken Telephone? Know how stories get distorted easily? Taking that into consideration, one would have to be INCREDIBLY arrogant to believe that anything they read in the scriptures were "correct", even if something supernatural really did take place. (Although in science, the "supernatural" is simply that which is not understood yet.)
And don't point me to any prophets who "correct" the scripture either, because prophets are supposed to be mere mortals, subject to the same flaws like you and me. The whole POINT of a prophet is not to mix up the Divine Message of God Almighty, and the mundane mortality of a shmuck prophet. For that same reason, it is also why consistently in Judaism, Christianity, and Islam, prophets are ALWAYS humble and hesitant to be a prophet. They are mere mortals, trash in the eyes of God. We must acknowledge their human limitations. Aside from the "Broken Telephone" phenomena, we know from modern Psychology that memory is fragile. Unless prophets were somehow "blessed" by God with superhuman abilities and memory, their testimony as a prophet is subject to question...
What about Jesus Christ? Isn't he more than human? Well, for one, he didn't write the bible, but his successors. And because his successors were mere human beings, they should be subject to question, because it is impossible for them to recall the story of Christ without very precise recording of history.
Psychologist Elizabeth Loftus found that the human memory is very flawed, and in fact the way we remember details are often incorrect, with only about a part of our memory being accurate, while our brain tries to make sense of it using imagination. In other words? Our memories are bullshit, and we likely couldn't remember a car accident 5 minutes ago. Don't believe me?

Listen, we have human limitations. You can claim all the faith you want, but you can't claim to be of genuine faith if you ignore reality of the way the human body works. Imagine how many religious "miracles" became a result of those false memories?
From Psychology alone, we can establish that monotheism is wrong if based on scripture alone based on prophets. From geography and history, we also establish that there is a world beyond monotheism, making it have quite the competition for anything "correct".
Now, like I mentioned earlier, I must establish that I am not against the spirituality or philosophy of Christianity or Islam. I am against scripture-based Monotheism, which asserts confidently its scripture to be correct.
If Americans are becoming less Christian, and more secular, know what my response is? "Good". Because the Bible isn't reality. The spirituality of Christianity might be correct, but the Bible is up to interpretation, and not exact whatsoever.
