The thing that mystifies me is how Brown, Shapira and such can remain Christians. I can understand them being lured to Christianity out of ignorance, but by now Brown (in particular) has been exposed to enough knowledge by the Rabbis -- how can he continue to pitch the same woo when he has to realize that he is wrong in so many areas? 
  
I've wondered about this too. Once a xian has questions, researches the answers, and determines the truth, how can they possibly continue to worship the xian idol? I think several converts to Judaism identified the reason. It's the fear factor, the fear of the devil and the eternity in a lake of fire. Fear is an extremely powerful motivator and it is difficult to overcome. The "what if its right" will always be in the back of their mind.

Personally, I think another reason is the inability of people to admit that they are (or were) wrong. Most people are unable to admit they were wrong on minor points, how much more so, on deep philosophical points. Rather than face their error, most people will rationalize or engage in doublethink, to continue erroneously believing.
