Explaining one side's viewpoint 10/5

In today's class, we did an interesting exercise. Rab separated the class in four groups and gave a task to write good points about his bag on two and bad points on another two groups. Our group got a task to write bad descriptions about Rab's bag. It is necessary to select the information which is not needed to explain the side of the view point we are going to write. What was surprising is our group eventually chose the words of bad discrimination to get the horrible impression and only look at the bad points. It was almost same trick as the British media used the word "kidnapped" in the conflict between Islam and Palestine. Put in mind in one direction often makes the view narrower. I would like to be careful not to have narrow viewpoints.
