It's by the force of argument and by the use of measurable statistics, which will be compelling to people who have open minds and an open hearts.
If they've made up their mind and if they're not interested in entertaining argument—that is to say that they dissent from their own position of “I don't know”.... This is a question for the ages: What do you do in a conversation if nobody wants to listen to you?
I happen to believe—I'm just built in a way that wants to believe—that most Canadians are open to reasonable argument and debate. If that assumption is wrong, then I wish all of us luck. I'm pretty certain that I'm not wrong. I have lots of evidence to think that people do change their minds. They change their minds when circumstances change. If they don't care about circumstance, then I don't think they have an open mind and I don't think they have an open heart.
I would remain optimistic based on that presumption of human nature, the Canadian national character and building on the success that we've already achieved together. I hope I'm right.
