What ever the argument was once based on, Knight is now -most certainly- taking the lead.
Delta is a fine sir with impeccable communications skills. As true as that may be, there comes a point where discussions with him meet a dead end. I am not implying Delta is factually dumb or lacks of further knowledge as per the subject in-discussion; simply that his theoretical views are, in many ways, self-shading and self-censoring. For the most part, the existence of limited liberty in one's opinions --or the lack of, for that matter-- inevitably abruptly affects it's value downwards. What could have been a ever-lasting yet interesting discussion, soon enough, becomes otherwise due to the lack of belief and trust put into the usual "thinking out of the box".
At the end;
Knight will always win, unless Delta does too.
(Wait, what?)
