Freedom of Expression

It is true that no body is perfect. Consequently, every body will face persons who like him and those who dislike him. Commonly, people who like us will view us from the good side and therefore, the can tolerate well to our mistakes. On the other hand, people who dislike us will view us from the bad sides and therefore they will too critical to us and cannot tolerate to our mistakes.

In the real world, like and dislike are two sides of a coin and they have very-very thin and transparent border. People who previously dislike to some body can eventually like him and the reverse. The logical reason is that people who dislike some body will look at him very-very in detail and this eventually will make them understand him well.

As the suggestion, don't hate somebody crazily and don't love somebody crazily or you will be really crazy.
