It's simple, Dave. AR282 hates organized religion sooooo much for some reason that he would simply love to prove that the man the Christians have based their entire set of beliefs on for the past 2000 years never even existed! It would absolutely make his day, and delight him to be able to prove that.

However, he is highly unlikely to succeed in such a Quixotic and impractical endeavour. ;-D

If he hated Buddhism, he would be similarly unlikely to succeed in proving that Buddha never existed. He is stating an emotionally biased and basically arbitrary opinion....one which he would prefer to believe is a logical certainty.
