William Kilpatrick argues that Islam is a religion of conquest, a reality he believes many in the West fail to acknowledge due to multiculturalism and a belief in religious equivalence. He contends that Christians must understand the fundamental differences between their faith and Islam to counter its advance, rather than seeking common ground. Kilpatrick also criticizes atheists and secularists, asserting they inadvertently enable radical Islam by undermining the Christian civilization that birthed Western liberties. This book calls for a reawakened Christianity to defend these freedoms.
