Actually, I do hold a VERY opinion of Christianity, and actually hold it as my personal faith. But I've been very distraught at the HUGE number of people in the world who claim to be Christians (probably a majority) who are in fact anything but - who have, using only the name of Christ (in vane) and the symbols and scriptures of Christianity, have created a cult of greed, war, vindictive judgement, hard-heartedness, hate, pride, nationalist and racism division, and promotion of elitism mixed with an unholy syncretic mess with inappropriate and jarring Gnostic and Manichaeistic (inappropriate and jarring as in they don't belong mixed). And this monstrous cult is a very large part of the laws and influence on most nations you speak of - as Christ, in his ministry, never spoke of theocratic legislation or political power by the Church; he was dismissive of government and wealth the few times he spoke of them. Also, for a proper Christian calendar that is spoken of, 1 AD would have to be pushed back to 3 BC in any case, and still screw up records.
