melmothtw,
Tony Blair is the sort of person that most people have strong views on - one way or the other. To try and persuade people in the opposite camp to see your point of view is probably pointless. Think of it as trying to persuade people that Hitler was a pretty good guy for Germany until 1938, building roads, getting the trains to run on time, etc....
By the way, I'm not a fan of Tony Blair (or Hitler for that matter!).
