The story I've read is "The Ugly Duckling". The theme of the story is acceptance. The story builds up the character of an ugly duckling and how he was bullied because of being different. His mother told him not to mind the other ducklings bullying him and go on walking. At the end, they discovered that he was not a duck, that's why he was different.
Martin Luther King was a man who wanted white and black have peace with each other without racism another black person can stay another white person can stay with no other way just peace and no violence
