Holy Jaboney, larc. Whoa!
I've enjoyed this interplay so far, but there has been a sea change. Clearly you are getting as serious as a heart attack on this one. You could easily have just given this guy the digitus impudicus/infamis, but now you have upped the ante (you must play mindless cards) and are nailing his callow ass to the xylon. Put up or shut up.
Now Duns is demonstrably naked and out of his league, which heretofore has been relegated to words for the sake of words, for the truly experienced vs. cognoscenti to see. He is not an elder!
Without question he has no experience in these areas; that is abundantly (ab unda: from the flood) clear for all who are experienced to see, and his tediously prolonged verbosity now rings hollow. He is seen to be the apologist that he insidiously is.
QED.
