The Politically Incorrect Guide to Islam by Robert Spencer, is a fascinating glimpse into the religion of one billion earthlings. Spencer is the director of Jihad Watch, a watchdog blog site that monitors jihadi activities in order to warn about upcoming violence from muslim terrorists.
Spencer has a video on YouTube where he is interviewed on his Politically Incorrect Guide, and presents an overview of his research into the Islamic tendency to violence--historically and in the present. Anyone who has looked at the history of Islam honestly will be tempted to agree with Spencer's assessment.
Spencer's ongoing work can be followed at Jihad Watch, and other websites. It is important that intelligent intellectuals (as opposed to indoctrinate PC pseudo-intellectuals) continue to dog the activities of the violent religious fanatics who make a comfortable home within Islam.
