As long as the Muslim population remains around or under 2% in any given country, they will be for the most part regarded as a peace-loving minority, and not as a threat to other citizens.
At 2% to 5%, they begin to proselytize other ethnic minorities and disaffected groups, often with major recruiting from the jails and among street gangs.
From 5% on, they exercise an inordinate influence in proportion to their percentage of the population. For example, they will push for the introduction of halal (clean by Islamic standards) food, thereby securing food preparation jobs for Muslims They will increase pressure on supermarket chains to feature halal on their shelves along with threats for failure to comply. At this point, they will work to get the ruling government to allow them to rule themselves (within their ghettos) under Sharia, the Islamic Law. The ultimate goal of Islamists is to establish Sharia law over the entire world.
When Muslims approach 10% of the population, they tend to increase lawlessness as a means of complaint about their conditions. In Paris, we are already seeing car-burnings. Any non-Muslim action offends Islam, and results in uprisings and threats, such as in Amsterdam , with opposition to Mohammed cartoons and films about Islam.
After reaching 20%, nations can expect hair-trigger rioting, jihad militia formations, sporadic killings, and the burnings of Christian churches and Jewish synagogues.
At 40%, nations experience widespread massacres, chronic terror attacks, and ongoing militia warfare.
From 60%, nations experience unfettered persecution of non-believers of all other religions (including non-conforming Muslims), sporadic ethnic cleansing (genocide), use of Sharia Law as a weapon, and Jizya, the tax placed on infidels.
After 80%, expect daily intimidation and violent jihad, some State-run ethnic cleansing, and even some genocide, as these nations drive out the infidels, and move toward 100% Muslim, such as has been experienced and in some ways is on-going in Bangladesh — Muslim 83%, Egypt — Muslim 90%, Gaza — Muslim 98.7%, Indonesia — Muslim 86.1%, Iran — Muslim 98%, Iraq — Muslim 97%, Jordan — Muslim 92%
100% will usher in the peace of ‘Dar-es-Salaam’ — the Islamic House of Peace. Here there’s supposed to be peace, because everybody is a Muslim, the Madrasses are the only schools, and the Koran is the only word, such as in: Afghanistan — Muslim 100%, Saudi Arabia — Muslim 100%, SomaliaMuslim 100%, Yemen ---Muslim 100%.
