The tales of the bhudda are equally fantastic and the lineage of the tales and teaching even more questionable than the transmission of the Jewish and Christian scriptures. And as you mention many of the interpretations of bhuddism are religious. None of which gets away from the fact that there is no evidence of rebirth or a cosmic law of justice. You like this worldview so you grant it a benefit you do not grant the Christian worldview. That is inconsistent.
Looking at your posts throughout this thread I am puzzled. You started off hardcore scientific atheist, then you were saying you were stoic (but one who did not feel he owed the world any duty, Marcus Aurelius would disapprove) now you claim bhuddism (but with a bellicose approach to Christianity, something a zen bhuddist would consider an attachment). You attack following a religious tradition of morals (because each religion has committed atrocities). You also attack anyone following their own personal interpretation (how can you trust an individual not to come up with a crazy and dangerous interpretation?).
Altogether this makes me think you're more interested a fight for a fight's sake than any search for truth.
