I've already posted about this, but Robert Spencer's article in FrontPage clearly shows D'Souza is clueless about jihad. Here's as small sample of D'Souza's willful ignorance.
Conservatives also must also “stop holding silly seminars on whether Islam is compatible with democracy. In reality, a majority of the world’s Muslims today live under democratic governments – in Indonesia, Malaysia, India, Bangladesh, Nigeria, and Turkey, not to mention Muslims living in Western countries. There is nothing in the Koran or the Islamic tradition that forbids democracy.” And “if they want Sharia, let them have it.”
Spencer rightly rips him to shreds.
