I don’t follow? What part of your post supports or denies your claim? Your opponent claims bacon is delicious, states that bacon gets it’s flavor from fat and then surmises that the fat alone must be better then bacon as a whole. I would assume he does not eat bacon fat in lieu of actual bacon but believes he has shown logic to be capable of absurdity. His inference seems true but his premise is false. Bacon gets some of its flavor from fat. Bacon fat is one reason that bacon is delicious. Logic!
osgood401 is, I believe, essentially correct. Your interlocutor seems to be arguing that the flavour of bacon comes exclusively from fat so that we should just leave the bacon to one side and concentrate on the fat. Hmmmm?
What exactly is the argument here? More to the point, how does it relate to what you wrote?
