It is not difficult, Bonzo. History cannot be changed. It has happened and there is nothing anyone can do about it. What happend here is that History was made. It is the point at which people said "we will no longer venerate slave traders". In future History books there will be the story of how we, the people of today, started to understand that everyone, regardless of race, colour or creed, has the same human rights. The 'Colston 4' will be part of that story.
