It is well-known that the purpose of the Muslim Brotherhood and their foreign affiliates is to islamize and dominate our societies. In France they control 40% of our Mosques, through the UOIF. Similar shares are observed in most countries. They think on the long-term, beyond this mere century.
Islamism is widespread, maybe a third to a half of Muslims. And most of moderate Muslims still support the idea of Muslim communities, which play in favor of Islamism. This is how many neighborhoods have been turned into Muslim places over the last decades, where the culture is Islamic and the rules and customs are more and more Islamist. Every year they number of such neighborhoods increases, and they become more radical.
Today in France, hundreds of thousands of brown people are forced to wear the veil and fast during the Ramadan. Because they live in Islamic places. White people in those places tend to convert under social pressure or to marry a non-Muslim, and others see their freedom being restrained, such as clothes for women, freedom of blasphemy, etc.
