What is the difference between acceptance and forgiveness?

When you forgive, you do not have to accept the situation of unfairness against you.  You can and should see what happened as unfair.  When you forgive a person, you offer goodness toward that person in an active way.  This can include kindness and even love in which you will the good of the other.  Acceptance of a person seems too passive to capture the essence of what forgiveness is.  You can accept a person’s actions without being either kind or loving.
