Has anyone ever changed your mind?

In all the debates you’ve engaged in throughout your life….has anybody ever profoundly changed your mind on a subject?

Common debates are: Abortion, Illegal Immigration, Gay Marriage, Religion, Politics, War, Animal Rights, Death Penalty, etc. As a result of a debate, was your view/perspective/stance significantly altered in any of these areas?

And, does debating actually accomplish anything other than giving us an arena to express our opinions?
