Proverb questions

So today being the 26th, I was reading Proverbs 26. I used the New International Version today
and verses 4 and 5 struck me.

(NIV) 4 Do not answer a fool according to his folly, or you will be like him yourself. 5 Answer a fool according to his folly, or he will be wise in his own eyes.

What?! Don't answer a fool then answer a fool. I've read this I don't know how many times and it didn't strike me until this day. So off I went for another version

(The Message) 4 Don't respond to the stupidity of a fool; you'll only look foolish yourself. 5 Answer a fool in simple terms so he doesn't get a swelled head.

Hmm, it says to not respond then answer. Still unclear...not quite sure about that one! Off to another translation

(New Living) 4 When arguing with fools, don't answer their foolish arguments, or you will become as foolish as they are. 5 When arguing with fools, be sure to answer their foolish arguments, or they will become wise in their own estimation.

So, it says don't answer then be sure to answer. Not really getting any help here! Okay, I'll try the King James Version and see what we get

(KJV) 4Answer not a fool according to his folly, lest thou also be like unto him. 5Answer a fool according to his folly, lest he be wise in his own conceit.

Whoa! That translation is the most unclear I have seen! Answer not a fool according to his folly followed by the exact same sentence with the 'not' removed. Not making a ton of sense, so I go to my commentary the Ryrie Study Bible in New American Standard

(NAS) 4 Do not answer a fool according to his folly, Lest you also be like him. 5 Answer a fool as his folly deserves, Lest he be wise in his own eyes.

Now that one makes more sense. Don't answer his silly arguments, but rather answer the underlying thinking problem. Get to the root cause of the thinking error. I can understand that. Ryrie's commentary doesn't really help here

These verses are complementary rather than contradictory. While it is unwise to argue with a fool at his level and to recognize his foolish suppositions, there are occasions when it is best to refute him soundly, lest his foolish opinions seem to be confirmed.

That doesn't clear anything up. It seems that we are to accept that it's okay because Ryrie says they complement each other rather than contradict but he doesn't explain how they complement each other.

So my conclusion is if we answer a fool it is not to be an answer to his incorrect arguments, but rather the underlying root thinking problem that he has.
