Religions, churches are institutions of men. When the leaders of institutions place themselves into the role of being absolute (God's) authority on Earth, bad things are bound to happen.
While I am not religious, I do like the check-and-balance system between the secular and religious that most Western countries have.
If the faith of a people leads them to have bloody thirsty beliefs, secular "balance" is pretty useless.
There seem to me to be fundamentalist factions on both sides. Each claiming to know "the will of God/Allah".
Just curious.
