Martin Luther King Jr. said....

Taken from purification of the heart:

The well-known civil rights activist Martin Luther King Jr. said that in order for people to condemn injustice, they must go through four stages. The first stage must ascertain that there are injustices being perpetrated. In his case, it was the injustices against the African-Americans in the United States. The second stage is to negotiate, that is, approach the oppressor and demand justice. If the oppressor refuses, King said that the third stage is self purification, which starts with the questions " Are we ourselves wrongdoers? Are we ourselves oppressors?" The fourth stage, then, is to take action after true self-examination, after removing one's own wrongs before demanding justice from others.
