Best-selling author Robert Spencer compares Islam with Christianity and shows that, far from being "sister religions" with similar core doctrines and morals, they're actually separated by "a great chasm" of belief and practice. A much-needed rejoinder to those who dream of an easy alliance between the two faiths.
