Bawer's book "While Europe Slept: How Radical Islam is Destroying the West from Within" (2006) concerns his belief in the threat that the rise of Islam in Europe poses to liberal values. Once established in Western European nations, Bawer maintains, Muslims avoid integration and answer only to sharia law, while avoiding the legal systems of their host nations, allowing abuse of women and gays, as well as Jews and other non-Muslims. In his conclusion, Bawer states that rising birthrates among Muslims and their "refusal" to integrate will allow them to dominate European society within 30 years, and that the only way to avoid such a disaster is to abolish the politically correct and multicultural doctrines that, according to him, are rife within the continent.
