Adaptive Buddhism (service, religions, Zen, Shinto, taoism)

It is often said, that Buddhism has the ability to absorb elements of other religions and culture. The first absortion, would probably be elements of Hindu. Arguments occur over Zen. Some people say that Zen is almost the same as Taoism. Others say Zen has borrowed certain aspects of Taoism.
