    Unlike China, where the majority of society belongs to the Han ethnic group, the United States is home to people from many different ethnic and cultural backgrounds, creating great diversity within its lively society.

However, historical events that created this diversity also led to racial disputes and prejudice that have lasted until today. Around days like Martin Luther King Day, people in the US are especially sensitive to racist comments and behavior.

Recently, a Facebook message posted by a white student at my boarding school started a wave of anger among African American students and started heated conversations about minority groups at the school.

The students posted an article written by someone else who stated that Robert E. Lee, a Confederate general during the US Civil War, should be commemorated(纪念). As the Confederates broke from the Union in order to keep slavery in their states, they were usually seen as racists. The post received a flood of comments from both white and black students within minutes, and conversation about the topic spread across campus quickly.

A fishbowl conversation was organized the evening the article was posted, and students and faculty (学院) members talked about their feelings and opinions. During the discussion, students from minority groups, including African American, Jewish, Asian and Indian students, spoke up about how they felt about living in a society mainly made up of people who are different from them. It turned out that many people felt isolated because of their differences from other people.

The diversity of society can open up interesting opportunities, but the great differences between people can also create huge gaps and misunderstandings if they are not treated carefully. Thus, effective communication is essential.

After the fishbowl conversation, the atmosphere in the school seemed to be changing, at least from my point of view. Students seemed to be talking and acting more freely than before, and the expressions of judgement were seen less on their faces.
