Why Are Christians So Defensive?

This movie is more historically correct than the bible for starters. There are two sources stating Hypatia was murdered by an angry mob. A neutral source and a Christian source.
Fact is there was a huge power struggle in Alexandrie with the Romans loosing their grip due to them converting to Christianism, between the Jews and Christians and Others (I don't like the negative conotation of Pagans).
Hypatia was a a tool in a filthy political game played mostly by the Christian leader Cyril. She was a scape goat and a very easy one at that, woman, unmarried and intelligent.
I don't think the Christians are worse than others in this movie, for once they are placed on the same level and not on a pedestal. Alle ZEALOTS commit crimes of any religion, that is the point here. It is the moderate and normal people that suffer.
There where clearly good Christians, as there where good Jews and Pagans, it is not the religion that defines that. But religion is used as a power tool and that is why it is often in my opinion a true poison for the people. Jezus would and will shudder in horror about everything that has been done in his name. Didn't you see the discussion between Davus and Ammonius? Davus doubts their actions and thinks Jezus would have forgiven, the zealot Ammonius doesn't even see the Jews they just killed as people, just because their jews.
Also big sins like killing someone are universal and punished in all religions. It is not just the Christians that know the difference between good and evil.
Christians should see themsemves as part of the world, not as above it, and also they should learn to self-critizise, very handy to stay on the straight and narrow.
This movie is a good first step.
