about calling ali god, the same way muslims force other religions to describe how their religion is monotheistic under pain of punishment or expulsion under their rule, christians also used to force other religions to explain how their religion is tritheistic, why don't you have a trinity like us? you must leave or die. calling ali a form of god was their way of doing that. today christians never do this (act like muslim extremists) but during the crusades they did and it created shia islam, alawites and druze too.
