How to fight against prejudiceprejudice can be found at any time and in any society. people have prejudice about another race, religion,nation and even about people who look different from them. it is known that prejudice appears when there isa lack of knowledge. that's because not enough knowledge leads to a generalization, which is the root ofevery prejudice. once people establish their general judgment about one particular group of people, they tendto keep their beliefs alive by ignoring facts that might spoil their judgment. they don't want to learn, becauselearning is generally hard and, what is more dangerous, it might also destroy their beliefs. people withprejudice never compare one individual to another, but one whole group to another group. but, what if thereis nothing to compare? imagine yourself in a foreign country, far enough to present big cultural differences between you andinhabitants of that country. what would happen with any prejudice you might have? could it still exist? ifthere is nothing to compare your prejudice will simply disappear because it will become invalid.next time, when you find yourself in a situation in which you have to fight against prejudice, try to imaginepeople of that group isolated from the others. that way you can successfully fight against any prejudice.a) is prejudice a recent issue? b) what kinds of prejudice are mentioned in the text? what other kinds ofprejudice do you know about? c) according to the text, what is the root of every prejudice? do you agree with it? d) should we generalize and stereotype people? why (not)? e) what advice is given in the last paragraph? do you think it's good advice? projectthis activity's contentcould be useful forproject 1, on page 81you may start takingnotes and developingyour ideas about it​
