This is not limited to just fanatics. Any person who is devoted to their religion puts a limit on their point of view. This is why organized religion promotes division among people. As the world gets smaller through technology and population growth, eventually (maybe in 100 years, maybe in 1000) everyone will have to adhere to the same worldview, and it ain't gonna be Christianity, Muslim, Judaism or any of today's religions (unless one dominates through genocide, and we know that ain't happening). You may be reading this with a bit of confusion if you know that a large part of my living comes from producing Christian music. The fact is, I'm not a religious person myself. I get paid to produce good music and I happen to live in a very Catholic town.
