I used the word 'primitive', but no-one could say I'm racist. My husband is an African.
I cannot comment on other religions, but Christianity as set out in the New Testament (not as twisted out of all recognition by strange cults, fundamentalists etc) is founded on the teachings of Jesus, and if one reads all the Gospels, one will not find any mention therein of torture, cruelty or savagery recommended as a remedy for 'possession'. I wholeheartedly agree that many many evil acts have been committed by people who maintained they were Christian . But they cannot have been. And I would venture that most religions are comprised chiefly of good people. Wickedness exists, but not only within religious groups, and even then, only in a tiny proportion of adherents.
