How many Christians do that, Rana? The vast majority of Christians condemn the things you mention above. The same cannot be said of Muslims, who, in the best case scenario, remain silent on the issue of terrorism.

For example, according to a survey conducted in Egypt, virtually the entire population believes that apostates should be executed. Sharia law is incompatible with human rights.
