I think the main problem is people forgetting the actual teachings and latching onto subjective beliefs that make them feel good. This is inherent not in any religion but in humanity itself. We set up psychological barriers. In atheists this translates to them attacking others who they see as less educated. In catholics this means distorting the teachings of the bible. It is no longer WWJD but "What would I do?"
The problem plagues humanity and i believe we will eventually evolve past it. We just need to come to an area of mutual acceptence, tolerance and understanding.
