why bother having a debate with someone who would lie and say that black is white just to win an argument?

For someone who thinks he is good at arguing, he is in fact crap at it.
His idea is to repeat the same thing in a loop until you say "OK you win". That's not a debate or argument. That's brow beating and bullying.

He would never agree to disagree - Only one way, his way.

he is like a dog with a bone when he gets started. He is not a very good person to debate or argue with because he thinks he knows it all and he is right. He won't open up to being proved wrong.

I would imagine an argument with JJ would be very tiring!
