Agnosticism is not necesaarily Atheism. Our doctrine is that you cannot know what happens after death until you experience it yourself. We do not condem other religions, because they may or may not be right. They only have faith that they are the 'true' religion. Most religious followers are exactly that; followers. They follow blindly, hoping that someday they will go to 'heaven' or something like that, it gives them hope and direction that most of them are not able to give themselves.
They are not allowed to question their religion, because if they did, they would find to many inaccuracies and hippocracies embedded in their faith. For example, most Christians know very little about the atrocities of the Crusades and The Inquisitions because they refuse to think that their faith was involved in such atrocities 'in the name of god'. In Christianity, it is a sin to question. Some recorded instances are interrogation of suspected 'witches' by ripping their fetuses from their wombs, and stomping on the child's head, telling the bound woman that she did that to her child by not confessing to being a witch. Another one I found quite disturbing was a case in which a small child was roasted alive over an open flame until the mother, father, and brothers would confess to heresy and suffer the same fate.
I recommend the books below for reading for those who would like to know more about the Crusades and Inquisitions:REFERENCES:
