 To challenge him. Normally you don't challenge your guests when you differ opinions. It depends. Not the way callers do, and I understand that. I understand the reason for that. As long as we're talking about the issue at hand, and as long as the attacks are levied against the ideas and not the person, I'll let them ride. It's when we get into name-calling, it's when we get into, you're an idiot or you don't see things clearly. Now we're attacking the person and not the argument. That's where I have kind of a short leash.
