Whether you're an atheist or not Jesus of Nazareth is the most important person in the history of western civilization, the Bible is the most important and influential literature in Western history, and the West's culture, music, art, social ethos, ethical history, education, hospitals, and science were profoundly influenced or even created by Christianity.
Attempting to sweep two thousand years of Western history under the rug with intentionally demeaning comments like fairytales, sky daddies, superstitions doesn't cut the mustard.
You, me, and nearly everyone on this board is the product of a Judeo-Christian civilization, and whether we admit it to ourselves or not, we have smuggled a cultural and ethical Christian ethos into our personal zeitgeist to one degree or other.
