Whats so offensive about Christianity

[robvalue]

I think it is likely he does know it is wrong, but he feels a compulsion to have to defend it at all costs. He would rather try and convince others, and himself, that a wrong is right, rather than consider his book may be wrong.

He has built the foundation of his world on this book. His whole life. To even consider for a second that he may have been wrong all this time is something so scary that he will use any kind of tactics to avoid it.

I'm not picking on drich, this is the case for most theists. It's a huge thing to consider you may have been wrong your whole life. It takes real guts, and often means standing up against those who have been feeding you those lies. Their brains have become experts at building an impenetrable wall around these beliefs, twisting and firing back any attempts to breach it without serious consideration.
