"Christianity is not based on history whatsoever, but the mere ravings of madmen".
Exactly!
I think Jesus went out on a serious bender for days on end and when he came home he told Mary that he was nailed to a cross and god brought me back to life. And Mary thought, two can play this game and told him that while he was away she conceived a baby to that very god.
"ravings of madmen" and the myth perpetuated by madmen.
All you have to do is visit a children's hospital or some of the poorest countries in the world and there is the proof that it was the ravings of mad men and swallowed by very naive people.
The mere fact that the world doesn't have one God doesn't raise an eyebrow?
