I know that sometimes "we" like to downplay the contributions of Jesus and it is easy to look back with our modern critical eye and say "Should have done this, should have said this, etc", but we also have to be honest and admit that the teachings of Jesus, if nothing else about him, deserve some respect and admiration.
Sure the message of love each other and the "golden rule" were around before him, but they were never applied to ALL people, just to which ever group it as aimed at and always with some form of recompense attached to it ( typically).
Fact is, we speak about these things because of Jesus and his followers, not because of what was written in some babylonian ( or other culture) writings that was aimed at a small group of people.
Even the devil is given his "due"...
