Religion in the modern world is completely unnecessary. But a little philosophy and good education will not hurt.
Religion - all of them - is just a convenient and irrational way to impose philosophic views. By impose conducts to society on this way instead of have to go through a hard and long rational discussion, which I believe was a hard to do with caveman, with little to no logical thinking abilities whatsoever, the philosopher takes a simply "because God(s) want". Making of it a discussion dead end.
