Tolerance to Other Religions in Different Religious Dogmas

The fact that eastern religions do not have a clear dogma on exclusivity of their faith compare to others, like for example traditional/pagan Norse or Hellenic religion doesn't have clear idea of exclusivity of Norse/Olympian gods, actually only means that either could be implied, not necessary that they accept existence of other non-Norse/Olympian gods. Japanese example of tolerance and coexistence between Buddhism and Shinto is rather a feature of Japanese society that anything from these religions themselves, since Japanese are also rather tolerant to other religions as well, not just to these two and for example Hindu followers are sometimes intolerant to other religions.
