Religion is a way of finding comfort. It is a source of security. A holder of tradition. An expression of Faith. I must agree, some people use religion as a shield to the fear of what is beyond. Though some use it to better there lives here as well as the lives around them. Some people use it to find something. Religion itself is a tool in life; something that can be used to help or hurt, only the possessor decides. Religion helps guide Faith. And as much as everybody needs Faith - Faith in something; anything really; that thing keeps you going. That burning ember that never fades. Faith in God, in Love, in knowledge, in tomorrow, in people, ect. - you don't need religion to express it. A person can be just as Loving and caring without religion as one with it.
And I think your chart is wrong. There are way more Jews than that. They have, like, 1/6th of the world's population. :c
Religion wars are loving stupid and I hate anyone who gets involved. There's other stuff to do.
And you're not going to make a difference at all whining on a forum.
Religion discussions can be quite nice, though. c:
