Sophisticated people always hide their prejudices. A sophisticated person would say, "it's not like this to me," instead of saying, "this is not the case at all. ".

If you find others' opinions totally unacceptable, try to change the topic.

If you are nervous about a topic, it will be dangerous to say anything. In other words, if you can only elaborate on your fixed viewpoint, don't mention this topic unless you are chairman of the conference.

On the other hand, if you can listen to someone's conversation in an open mind, you can speak safely. In conclusion, any mature and interesting topic can cause you to disagree.

Be careful! Unless you can debate without sarcasm, you'd better withdraw from the debate. If you have a cool head, you will be able to debate with your opponent skillfully. It will be a very interesting game, but it is dangerous for people who are hot headed and bad tempered.
