@au1929,
I agree that religion is a fabrication of man, but that does not necessarily mean there is no truth at the core. Anything can be a religion because a person can do anything religiously. I can watch ESPN religiously every day. That could be my religion.
I disagree however, that Christianity and other such faiths have caused damage in a drastically significant way. Don't get me wrong, people were killed, burned at the stake, and treated like animals for not believing a certain way through the pages of history and it is tragic and wrong. But religion is not the problem, it's any strong belief or feeling of superiority that is the problem. You may recall the millions upon millions upon millions killed under Stalin's atheistic regime in Russia in the 1930's.
On the whole, all religions encourage people to treat each other well. It's when that power and that thought of superiority is used and abused by people of any belief, whether religious or atheistic, when it causes problems. It's the individuals who make these things happen under the guise of religion and belief.
