Tolerance can be defined as the ability to accept diversity and to live and let others live. Without tolerance the lasting peace of societies cannot be maintained. Lack of tolerance destroys the peace of society. When people fail in their arguments, they become intolerant, and they use force and aggression to support their point of view.
It isn’t simple to be a tolerate person. It is ok to stick to your own values, but it makes sense to evaluate your values, specially if they are having an effect on others. It needs to be clear that everyone has their own opinions and values and that these need to be respected and accepted. If we want to live in a peaceful society, there is no alternative to tolerance.
