According to Kennedy's address, the idea that must be changed is that black people are less worthy than white. Basically, it's an idea that freedom has limits. If freedom exists in the United States, it must exist and be applicable to everyone, including the African American citizens. If it excludes anyone, based on any feature, it is not freedom at all. Freedom is the basis of American Constitution. It is one of the pillars of American national identity. So, it must be available and guaranteed for everyone. The change is necessary because it is time to start employing this idea that had been abstract for an entire century. By changing this idea, the American society would become a society of equals, with each and every citizen's fundamental human rights being protected and guaranteed.
