* Islam seeks to replace European civilisation and values with its own. It envisions a Europe where Islam is the dominant religion, and sharia replaces the European legal tradition.
* Western civilisation is explicitly Judeo-Christian, and the Islamic hostility is partly religious.
* Muslims make continual demands in order to impose their own values, and concessions inspire fresh demands. Most if not all Muslims have this demanding attitude, since such demands are a part of their religion.
* These demands are also intended to place non-Muslims (primarily Jews and Christians) in the status of dhimmi, and most Muslims find that the only appropriate status for them.
* These demands should be resisted, but European governments, media and elites consistently fail to do so. They even pre-emptively make concessions to Muslims, including self-censorship. Their attitude is that of dhimmitude - the servile attitude of the weak dhimmi in a Muslim-dominated society. Dhimmitude is seen as effectively an act of treason against Western Civilisation.
* Muslim immigration to Europe is a strategy, intended to gain control of Europe, by replacing its non-Muslim population with Muslims - it is not primarily economic in character.
* The growth of the Muslim population in Europe by natural increase (high birth rates) is also part of this strategy - "outbreeding the enemy." There are already many more Muslims in Europe than official statistics admit -- with some countries like France and Belgium refusing to even count their minorities -- and within several generations (at least by 2100) they will form a majority. European governments have actively facilitated this strategy by allowing continuous immigration from Muslim countries, which is also tantamount to treason.
* Even before they are a majority, Muslims will dominate European politics because of their numbers and the complacent dhimmitude of politicians and elites, who consistently fail to offer any resistance to them.
