In
the first letter, there were 4 kinds of answers and some of 6 people said they heard from someone or someone told them about it. Therefore, they might have wrong information or misunderstanding. They did not see the discrimination that they answered but they believe what other people said. However, others used the authority like giving an example. They have seen such discrimination as they answered so their opinions are more reliable and more persuasive than former people who I mentioned.
The writer of response to the first letter said it depends on where you live which minority groups face the worst discrimination. He lives in Nagasaki and he wrote about his experiences of being discriminated so there was much information in
his letter. I think the behavior some Japanese people did to him was really bad and is not allowed. However, I do not think Japanese people hate Americans because more and more Americans come to Japan and I have never seen such situations. Some old Japanese people might have prejudice but such people are few. If he thinks many Japanese people hate Americans, he should use a generalization to tell that Japanese people do such things like he mentioned in his letter not only toward him.
What is the most important in his letter is discrimination does not depend on places. Some Japanese handicapped people are actually discriminated even in Japan, that is, place does not matter. The discrimination can be happen everywhere all over the world.
