I suggest fewer words, sharpened points, and more focused questions.
Proverbs 17, verse 27:
(KJV) He that hath knowledge spareth his words: and a man of understanding is of an excellent spirit.
(NLT) A truly wise person uses few words; a person with understanding is even-tempered.
Proverbs 16, verse 21:
(KJV) The wise in heart shall be called prudent: and the sweetness of the lips increaseth learning.
(NLT) The wise are known for their understanding, and instruction is appreciated if it's well presented.
There's no need to prove foolishness through tactical questions, as it's obvious to those with understanding.
