Douglas, you have an incredible capacity for missing the point. Will you listen to me, just for once? The debate does not matter. It's not about the issues. Albie might have been naive or ridiculous or pompous or all of those things, but you apologized. You said you were embarassed by him. You took the side of a bunch of arms-dealers! Bloddy bastard arms-dealers against your son - our son - and that was wrong, it was the wrong thing to do, because in a fight you side with the people you love. That's just how it is.
