Prejudice does not come from nowhere. It is the product of repeated occurences. You pre-judge constantly throughout the day. Otherwise how would you know that the next sandwhich isn't poisonous? It might be. But your prejudice tells you that most bread isn't full of cyanide.

The same idea can be applied to people to get "racism". From repeated incedince I have a prejudice (or racist idea) that black people are more often mesomorphs than white people. Which is a good thing for black people.
