I guess he meant "contraception", Amos. (grin)

Good stuff, Giok. I actually wasn't quite sure what you were driving at in your orginal post. Yes, I think prejudice is usually due simply to ignorance. If one gets the chance to become familiar with a different lifestyle and see where the people are coming from, one usually gets to like them and the prejudices vanish. When people are ignorant of something they tend to make all sorts of bizarre and mistaken assumptions about the "other" and they also tend to fear that other on some level. Irresponsible political regimes use that fear to motivate people to go to war against those they perceive as different from themselves. If they actually knew those people better they would probably not be nearly so willing to go out and kill them. They might even grow to love them.

Pied Piper - Well said.
