Why do Christians keep attacking people who has doubts?

I will give you the BEST answer I can possibly give you. I will NOT however give you the ANSWER as I nor anyone else has it... Watch ZEIGIEST both of the Movies... you will then have a ground base for you beliefs, arguments etc... then go back and RESEARCH all the name, their history their accounts, see if the aforementioned are VALID. You can find the movie on Youtube...
