True, any section of society has a set of characteristics that distinguish it from everybody else. However, that does not necessarily mean it must be hostile to others. Interfaith would be between faiths, and even if one feels their faith is the correct one, that does not mean they have to exclude or suppress the others. It seems to me that most religious faiths are built around some basic core principals that are common or similar to most faiths. Then there is this whole trapping of dogma, ceremony, and costumes that humans build around it. Often they surround the internal kernels of truths or spiritual beliefs with so many trappings that it becomes hard to see what the original faith was built upon. This using God's name for vain human purposes is a regular epidemic in religions, not withstanding the third commandment that the Abrahamic traditions claim to hold sacred. As I recall Jesus went off on the religious authorities of his day with his seven woes- Matthew 23.
