Sarcasm aimed at those who believe what I wrote.

i think he meant someone was a dunce, which has kind of an interesting derivation: dunce [dʌns] n a person who is stupid or slow to learn [from Dunses or Dunsmen, term of ridicule applied to the followers of John Duns Scotus (?1265-1308), Scottish scholastic theologian and Franciscan priest, especially by 16th-century humanists]
