Analysis:
This situation is a typical example for racial discrimination. In the picture, we can see easily a black and miserable man standing beside a fence. Maybe, he gets into trouble and needs help. However, because of racism discrimination, people only support for the white, not the black. The negative attitudes towards the black make the man doesn’t get help from other people. It is very wrong and unfair.

Item 2: Prejudice
Đàn ông nông nổi giếng khơi,
Đàn bà sâu sắc như cơi đựng trầu.
Analysis:
This saying shows a striking contrast between men and women in their thoughts and behaviors. It is said that men usually have profound thoughts than women. The ancient people have taken two objects that are common in rural areas to illustrate the difference in a well and a betel container). Needless to say, the former is deeper than the latter. However, people use chiasmus to emphasize the difference. As I mentioned, it is unfair. Nowadays, there are many women who are more mature and decisive than men. They play an important role in the society and have many chances to expose their ability. Therefore, we should not judge people without knowledge of the facts.

Item 3: Scapegoating
During the 1980’s AIDS epidemic, homosexual men were stigmatized and accused with causing the disease.  Muslims are scapegoats for every terrorist attack takes place in the globe. Hitler is blamed for causing the start of the  second world war.

Analysis:
All examples are scapegoating . Although those people (homosexual men, muslims, Hitle) are not the causers, they are blamed for the some above communities’ problem. This thing is very unfair. Therefore, before reaching conclusion, people should think carefully to avoid scapegoating.
