Why Presuppositional Apologetics?

Proverbs 26:4-5 NIV[4] Do not answer a fool according to his folly, or you yourself will be just like him. [5] Answer a fool according to his folly, or he will be wise in his own eyes.

Presuppositional apologetics supports a biblical position on apologetics. It also does not enable the unbeliever’s foolishness. The unbeliever is satisfied when you use evidential apologetics. This allows them to ignore their folly. 

Enabling the unbeliever is not loving them. Helping them suppress the truth they know is not loving. 

This was recently seen during a conversation I had with an unbeliever on Google Plus, and I pasted the screenshot of his reply. 

When I was using evidential apologetics, I gained the approval of the unbeliever. When I switched and used the word of God as my foundation, the unbeliever couldnno longer ignore their folly, must face the truth they already know, and greatly disapprove of that approach. 
But which is more loving? Which approach readies the unbeliever’s heart for the gospel?

Presuppositional apologetics is the biblical method that stays true to God’s word, glorifies Him, and is most loving towards the unbeliever.
