The 29 minute video went into this diatribe about the various Christian groups, and how they treat Christians according to Islamic law, whether by jizya under dimma status, by conversion for full rights, or death. They showed examples of the jizya paying Christians in Iraq (probably staged) on how "peaceful" they live in ISIS when paying jizya. They then showed examples of those who apostatized into Islam, and they were Africans, who vowed the shahada. Finally, they showed the brutal killing of the 30 Ethiopians who refused to pay jizya (or probably did not have the money to pay it) or convert.
They were given a chance to convert and they did not take that chance. They chose the eternal glory with Christ over the falsehood of renouncing Christ and the Church. May their prayers and the prayers of the 21 Coptic martyrs be with us all!
