Miss Maudie cites the trial as a baby step? What does she mean? What is our author trying to say about the morals of an individual and community?

I think that she realizes that the town knows their shame. There is very little said about the trial after it is over. The town knows the truth and Atticus has set in their mind how wrong their verdict was. Miss.Maudie thinks this is a first baby stem for people to reflect about their bigotry.
