This video's mean idea is telling us if this world without hate, it gonna be a peace, friendly, and positive world. It displayed some of famous people. Their achievement can be a story was told by people. I can imagine there is no hate in their brain. I believe they are have a commom ground in their mind that is make contributions to society.  But live is not always like us imagine. There are still a lot of people has impacted by cyber bullying. I think every children should be education in the primary school, and this video is a great material.  People needs love, world needs love, let's forget about hate, be a nice person, do something for this world!
