Not doubting this voice in the wilderness, but, what passage in the Quran is he talking about? "Instructed by the Koran to lie low until they reach 10% of their host-countrys population..."
It is not a pasage in the Koran. "In the early years of the Islamic conquest of the Arabian peninsula and in the Fatah (Arab-Islamic invasion and conquest of the upper Middle East and the outside world), a Muslim concept was devised to achieve success against the enemy (non Muslims), Al-Taqiyah. Al-Taqiyah, from the verb Ittaqu, means linguistically dodge the threat. Politically it means simulate whatever status you need in order to win the war against the enemy ..." They can lie, cheat, rope-a-dope, or do anything to bide time and regroup for the next assault on the infidels.
Islam is a virtual nation. They have no allegiance to the Western countries in which they reside. Muslims are so brain washed they will passively support any atrocities commited on infidels. Their is no hope for civilizing them. Their citizenship shuld be revoked and they should be deported in mass to countries in the middle east or Somalia.
