Understand this debate technique, think of the last time you had a debate with a beggar:
"Got some change for oxy - I mean, coffee?"
*stares blankly ahead, walks on by*
You don't give them anything to work with. Most people debate by responding to what the other person just said, so if you provide nothing, you stump them.
"Why won't you accept Jesus?"
"I dunno, I just won't"
"Why don't you want eternal bliss?"
"I dunno, I just don't."
"Why don't you want to escape hellfire?"
"I dunno, I just don't."
The ignorance renders them invincible.
We can also use this trick, remember our slogan:
"God said it, I believe it, that settles it".
