If we can live with and enjoy every person we think stupid, and everyone who thinks we are stupid, maybe world peace is just around the corner. Psychology believes that the lower the self-worth, the more habitual it is to seek out and rely on Self-confirmation of relationships with others. In this process, the "stupidity" of others will become a frame of reference that is popular and fragile, and the "no stupidity" will become an attack that hides powerlessness. Therefore, we need to organize ourselves Goals, status quo and feelings, determine our value, rather than set off our own wisdom through the stupidity of others, and confirm our strength with the exclusion and suppression of others. The most accurate summary of the core point of this text is:. ['We must learn to live peacefully with "stupid".', 'Why do we attack "stupid" people.', 'We need to practice to change the way we coexist with others.', 'People who use the exclusion and suppression of others to confirm their strength are often those who lack self-worth.']
