There's a way in which all of these grazers at the spirituality buffet are performing a service, because you could argue that grazing leads to a kind of tolerance. People who incorporate teachings from a lot of different traditions into their own belief systems are going to be more tolerant than people who confine themselves within the strict boundaries of one particular religion. Does it contribute to our confusion? I don't know if it contributes to confusion so much as it is evidence of a certain kind of silliness and shallowness.
