Strange how mankind seems to be hard wired to myth and superstion let alone when this is organised for him into theism by some form of central authority usually cultural/political. It is more than just cognitive dissonance or lack of education/child brainwashing. So since Asian part of mankind how come escaped?
When you talk of the east, you seem to think only of China and India seems to be out of your mind. Yes, there were no wars here because, as you say, "our god is better than your god" reason because Hindus' in particular and Indians in general are benign people. In spite of this, Hindus did face the 'our god is better than your god" attitude of the muslims for a period of at least several hundread years. Stories of demolished temples still rankle in Hindu minds.
You're right, but that has nothing to do with modern Judaism. And when the person mentioned the Big 3, I'm sure he wasn't referring to Pre-Christian times.
But if you really want the low-down, the Jews stopped proselytizing because they were forbidden to do so by the Christians on pain of death -- can't have any competition, you know!
No, the orientals have not escaped. The biggest religion in this part of the world is Hinduism and Hindus still are highly religious and even superstitious. Much of the east is also Muslim, and they are well ahead of Hindus in this respect.
