WWJD, not say fukk buddha that's what. Buddha came 500 years before christ, AND preached to a much larger population which was far more enlightened and conscious than the desert dwellers of the middle east. If anything, had he claimed to be (which he didnt) God's son, I'd have actually believed that. His life was documented very detailed. He spoke many truths, and basically told humans to keep an open mind with everything (leaving evolution of the mind and consciousness an option) all while giving the east mortality (thats what religion was, the conscious awakening of mankind from barbarism to morals.)
Christianity barely exists in the East, Buddhism is their version of Christianity, but alas, here you are talking about fukk it.
