Pan, objectively speaking, I don't see where Smeth "attacked" you. He disagreed with your factual position and supported it with his own set of facts.
Unfortunately there are no degrees of truth here. It's an absolute truth that pledged delegates HAVE to vote for their man (or woman on the Democratic side). Those are the rules of both parties and there's zero room for the elected delegates to change their minds. They will be thrown out of the convention and their vote stricken if they don't vote their pledge. They probably won't be back to any future conventions either.
Sorry, but you're mistaken in how you're interpreting this. In other words, you're wrong.
