The Fires of Religious Animosities
So much bloodshed occurred in the Christian sects and Muslim sects themselves. Many were killed over discords in beliefs.
The same attitude exists even today. The discords of Christians in Cyprus were not long ago, and there are still hidden animosities, and the discords between Muslims, Christians and Jews in Palestine are still persistent. War and bloodshed are still in India between Muslims and Hindus, and discords and fratricide still exist among Protestants and Catholics (which both follow the same religion) in Ireland.
