It is to say NO to prejudice. Because hate, misunderstanding, fear and jealousy drive some people to attack, destroy others and take what they have. But after a war , the loser feels humiliated and often wants revenge. Being tolerant means resisting peacefully when threatened with violence. It means being strong to protect the weak.
Tolerance is respect for all who live on earth now and in future generations.
It means supporting one another. It's working together to fight violence, poverty and intolerance. In a family , people have to life together. Firstly, by being more tolerant with ourselves. By keeping a sense of humour and by accepting our faults and mistakes.
