Any person who is completely for one side of an issue is naive and ignorant. Issues and debates exist because there are no clear cut answers. Rarely in life is anything black and white. Any truly intelligent person will concede that the opposing viewpoint has some valid points, even if they only apply in certain circumstances. The goal of debate should not be to overpower and win over the other side, but to expand the intellectual horizon of both parties; only then is any argument truly useful. The strongest argument is an example that proves there are exceptions against any generalization. If, at the end of the discussion, both sides feel they have learned something new, if both sides have gained a new perspective, then the discussion was truly useful.
