Mrrzy,Its not so much Religion, as the things those claiming to be Religeous do, in its name... its what those 'invisible friends' are whispering in their ears, or what they CLAIM they are getting whispered to them.
Religion can draw a line between two people, or between two Peoples......if you see what I mean. Then it becomes easier for them, to see the people on the other side of that line as 'less' in whatever way, than themselves...
